title: Security

text:
#### Open source Redis security fixes compatibility

As part of Redis's commitment to security, Redis Enterprise Software implements the latest [security fixes](https://github.com/redis/redis/releases) available with [open source Redis](https://github.com/redis/redis). Redis Enterprise has already included the fixes for the relevant CVEs.

Some CVEs announced for open source Redis do not affect Redis Enterprise due to different or additional functionality available in Redis Enterprise that is not available in open source Redis.

Redis Enterprise 7.2.4-138 supports open source Redis 7.2, 6.2, and 6.0. Below is the list of open source Redis CVEs and other security vulnerabilities fixed by version.

Redis 7.2.x:

- RedisBloom: Cuckoo filter counter overflow.

- RedisBloom: Invalid Bloom filters can cause arbitrary memory reads and writes.

- RedisBloom: Reachable assert in `TopK_Create`

- RedisBloom: Out-of-bounds access with empty Bloom chains.

- RedisBloom: Division by zero in Cuckoo filter insertion.

- (CVE-2025-46818) An authenticated user may use a specially crafted Lua script to manipulate different LUA objects and potentially run their own code in the context of another user.

- (CVE-2025-46819) An authenticated user may use a specially crafted LUA script to read out-of-bound data or crash the server and lead to subsequent denial of service.

- (CVE-2025-46817) An authenticated user may use a specially crafted Lua script to cause an integer overflow and potentially lead to remote code execution.

- (CVE-2025-49844) An authenticated user may use a specially crafted Lua script to manipulate the garbage collector, trigger a use-after-free, and potentially lead to remote code execution.

title: New features

text:
#### Redis 7.0 features

The following Redis 7.0 features are now supported:

- [Redis functions]()

    In Redis Enterprise Software, [`FUNCTION STATS`]() returns an extra parameter, an array called `all_running_scripts`, to reflect multiple functions running at the same time.

- [Multipart AOF](#append-only-file) (append-only files)

- New commands

- Sharded `PUBSUB` (see [Sharded pub/sub](#sharded-pubsub) for details)

#### Redis 7.2 features

The following Redis 7.2 features are now supported:

- Various performance improvements

- `CONFIG SET` for locale

- Connection layer modularization

- Encoding improvements: listpack for sets and lists

- Observability: authentication metrics (exposed by `INFO` command)

- Stream consumer group improvements

- Commands: `ZRANK`, `ZREVRANK` new `WITHSCORE` option

- Shard IDs in cluster shards topology

- Introduce shard ID to Redis cluster

- Support `CLIENT NO-TOUCH` command

- `WAIT AOF`

#### Auto Tiering - Redis on Flash evolution doubles throughput and reduces latency {#auto-tiering}

Redis Enterprise version 7.2 introduces Auto Tiering as an enhanced successor to Redis on Flash, which allows you to provision larger databases at a lower cost by extending the RAM with flash drives.

Redis Enterprise Auto Tiering replaces RocksDB with [Speedb](https://www.speedb.io/) as its storage engine, doubling the throughput and reducing latencies, achieved using the same infrastructure resources. For example, a 1 TB database with 50K ops/sec can now serve 100K ops/sec based on the same infrastructure.

To switch existing databases to use Speedb for Auto Tiering and improve performance:

1. Upgrade the cluster to Redis Enterprise Software version 7.2.4.

1. Upgrade each database with Auto Tiering enabled to Redis database version 7.2.

For more information about Auto Tiering, see:

- [Auto Tiering overview]()

- [Auto Tiering quick start]()

#### RESP3 support

Support for RESP3 and the [`HELLO`]() command was added in Redis Enterprise 7.2.

To use RESP3 with Redis Enterprise:

1. Upgrade Redis servers to version 7.2 or later.

    For Active-Active and Replica Of databases:

    1. Upgrade all participating clusters to Redis Enterprise version 7.2.x or later.

    1. Upgrade all databases to version 7.x or later.

1. Enable RESP3 support for your database (`enabled` by default):

    [code example]

If you run Redis Stack commands with Redis clients [Go-Redis](https://redis.uptrace.dev/) version 9 or [Lettuce](https://redis.github.io/lettuce/) versions 6 and later, see [client prerequisites](#client-prerequisites-for-redis-72-upgrade) before you upgrade to Redis 7.2 to learn how to prevent potential application issues due to RESP3 breaking changes.

#### Sharded pub/sub

[Sharded pub/sub](#sharded-pubsub) is now supported.

You cannot use sharded pub/sub if you [deactivate RESP3 support]().

#### New Cluster Manager UI preview

A preview of the new Cluster Manager UI (admin console) is available in Redis Enterprise Software version 7.2.4.

To try out the new UI:

- On the sign-in screen:

    1. Enter your credentials.

    1. Select **Sign in the new interface**.

- Sign in directly from the new UI's sign-in screen at <nobr>`https://<hostname or IP address>:8443/new`</nobr>

- If you are currently signed in to the legacy UI:

    1. Select **Switch to the new Admin Console** to expand the banner at the top of the screen.

    1. Click the **Try it now** button to open the new UI in another tab.

##### New UI benefits

- User-driven design

- Provides full functionality to complete tasks entirely in the UI

- New attributes and improved feature visibility

- Provides configuration flexibility while highlighting the recommended path

- Addresses the needs of different personas and use cases

- Quicker troubleshooting and easier maintenance

##### New UI highlights

- More configurable database attributes, including replica high availability, shards placement, and proxy policy.

- Nodes indicate whether it’s a primary or secondary node.

- Modules show the databases that are using them.

- Certificates show expiration and validity, and you can upload and copy certificates.

- Cluster license displays the number of shards that are used out of the number of shards that are licensed to the cluster. The new UI allows you to paste or upload a new license.

- Role-based access control (RBAC) has explanations to improve clarity.

- Access Control List (ACLs) now support defining ACLs for modules.

- The databases screen has more information per database for faster troubleshooting. It also allows you to filter databases and compare database metrics.

- The cluster name, user, and user role are shown in the upper right for quickly identifying the cluster from any screen. You can also **Change user password** from the dropdown menu.

- Auto Tiering licensing and a toggle for the storage engine used in Auto Tiering enabled databases (available only in the new UI).

- Input validations.

##### New UI limitations

The following features are not supported in this preview but will be added in future releases. Until then, temporarily switch to the legacy UI to do the following:

- Provision and configure Active-Active databases (viewing is available).

- Search and export the event log.

- Remove a node from the UI.

Additional limitations:

- Although Redis supports memcached databases, the new UI only allows view and delete. Memcached users are advised to migrate to Redis to enjoy the full benefits of Redis and its UI.

To open the legacy admin console when signed in to the new UI, select your username, then select **Switch to legacy Admin Console** from the list:

##### Future UI enhancements

- Configure default database settings and database upgrade settings

- Security preferences related to password and login management

- LDAP improvements

- IPv6 support

- ACL improvements, such as ACLv2 smart validations

- And more

With the release of the new Cluster Manager UI, the legacy UI is considered deprecated and will eventually be phased out. New functionality will only be implemented in the new Cluster Manager UI, and the old UI will no longer be maintained except for critical bug fixes.

#### Redis Stack 7.2 features

Redis Enterprise Software version 7.2.4 supports features included in Redis Stack version 7.2.

The following sections include a few highlights. For more details, see the [Redis Stack 7.2 release notes](https://github.com/redis-stack/redis-stack/releases/tag/v7.2.0-v0).

##### Search and query

- Introduces [Geo Polygon]() Search. Geo range queries now accept the [`GEOSHAPE`]() field type, which supports polygon shapes using [WKT notation](https://en.wikipedia.org/wiki/Well-known_text_representation_of_geometry). `GEOSHAPE` supports `POLYGON` and `POINT` as shape formats and polygon operations.

- Performance improvements for `SORT BY` operations using [`FT.SEARCH`]() and [`FT.AGGREGATE`]().

- New `FORMAT` for improved readability and future support for better error handling responses on `FT.SEARCH` and `FT.AGGREGATE` in RESP3 only.

##### JSON

JSON introduces two new commands:

 - [JSON.MERGE]() merges a given JSON value into matching paths to update, delete, or expand the JSON values at the matching paths.

 - [JSON.MSET]() sets or updates one or more JSON values according to specified key-path-value triplets.

##### Triggers and functions preview

A preview of triggers and functions is available.

Triggers and functions provide support for running JavaScript functions inside the Redis process. These functions can be executed on-demand, by an event-driven trigger, or by a stream processing trigger.

Try it out with the [triggers and functions quick start]().

- The preview version of triggers and functions is not intended for production use since the API might change in the future and potentially cause application issues when upgrading to a later version.

- During preview, triggers and functions are not supported for databases with Auto Tiering enabled (previously known as Redis on Flash).

##### Module versions

Redis Enterprise Software version 7.2.4 includes the following Redis Stack modules:

- [RediSearch 2.8.4](https://github.com/RediSearch/RediSearch/releases/tag/v2.8.4)

- [RedisJSON 2.6.6](https://github.com/RedisJSON/RedisJSON/releases/tag/v2.6.6)

- [RedisTimeSeries 1.10.4](https://github.com/RedisTimeSeries/RedisTimeSeries/releases/tag/v1.10.4)

- [RedisBloom 2.6.3](https://github.com/RedisBloom/RedisBloom/releases/tag/v2.6.3)

- [RedisGears 2.0.11](https://github.com/RedisGears/RedisGears/releases/tag/v2.0.11-m12)

For Redis Enterprise Software version 7.2.4, `default_redis_version` is 7.2 for both `major` and `latest` upgrade policies.

#### Updated Redis Enterprise license format

Redis Enterprise Software version 7.2.4 includes updates to its license format, which add separate shard limits for RAM and flash shards used for Auto Tiering.

For more information, see [Cluster license keys]().

#### Redis ACL selectors and key-based permissions

Redis ACLs in Redis Enterprise version 7.2 support key permissions and selectors.

Key permissions:

- `%R~<pattern>`: Grants read access to keys that match the given pattern.

- `%W~<pattern>`: Grants write access to keys that match the given pattern.

- `%RW~<pattern>`: Alias for `~<pattern>`. Grants read and write access to keys that match the given pattern.

    See [key permissions](#key-permissions) for more information.

Selectors let you define multiple sets of rules in a single Redis ACL (only supported for databases with Redis version 7.2 or later). A command is allowed if it matches the base rule or any selector in the Redis ACL. See [selectors](#selectors) for more information.

- `(<rule list>)`: Creates a new selector.

- `clearselectors`: Deletes all existing selectors for a user. This action does not delete the base ACL rule.

Redis ACLs have the following differences in Redis Enterprise Software:

- Nested selectors are not supported.

    For example, the following selectors are not valid in Redis Enterprise: <nobr>`+GET ~key1 (+SET (+SET ~key2) ~key3)`</nobr>

- Key and pub/sub patterns do not allow the following characters: `'(', ')'`

- The following password syntax is not supported: `'>', '<', '#!', 'resetpass'`

    To change passwords in Redis Enterprise Software, use one of the following methods:

    - Cluster Manager UI (admin console)

    - [`rladmin cluster reset_password`]():

        [code example]

    - REST API [`PUT /v1/users`]() request and provide `password`

- The **ACL builder** does not support selectors and key permissions. Use **Free text command** to manually define them instead.

#### New INFO fields

The [`INFO`]() command includes new fields:

- Under the `STATS` section:

    - `current_eviction_exceeded_time` - Redis Enterprise reply is always "0"

    - `total_eviction_exceeded_time` - Redis Enterprise reply is always "0"

    - `current_active_defrag_time` - Redis Enterprise reply is always "0"

    - `total_active_defrag_time` - Redis Enterprise reply is always "0"

- Under the `MEMORY` section:

    - `maxmemory_policy` - The value of the `maxmemory-policy` configuration directive

The `INFO` command can now accept multiple section arguments (requires Redis database version 7 or later).

#### Log rotation enhancements

- The `logrotate` tool rotates logs that exceed 200 MB.

- `logrotate` runs every five minutes instead of once a day.

- The job scheduler runs `logrotate` instead of the OS.

- Every cluster upgrade overwrites the log rotation configuration.

- You can edit the log rotation configuration at `$pkgconfdir/logrotate.conf` (`pkgconfdir` is `/opt/redislabs/config` by default, but can be changed in a custom installation). Note that the configuration file moved since last version.

- You can change how often the `logrotate` tool runs using the job scheduler REST API request <nobr>`PUT /v1/job_scheduler`</nobr>.

#### Multi-OS upgrade support for clusters with modules {#os-upgrades-with-modules}

Starting from Redis Enterprise version 7.2, all future 7.2.x upgrades are supported for clusters containing databases with modules in combination with Operating System (OS) upgrades.

title: Resolved issues

text:
- RS54131 - `+OK` reply not received on TLS-enabled database

- RS101525 - Cluster provides wrong number of database connections on Grafana

- RS104028 - Fix the self-signed certificate script: error generating certificates with multiple FQDNs

- RS87920 - Proxy log is full of the warning message "Failed to check status of running child syncer process 0 : No child processes"

- RS99916 - Fixed the UI log to include the names of LDAP users at login

- RS84273 - When an LDAP user with a Redis `admin` role viewed the log in the UI, they received `db_viewer` permissions instead of `admin`, which limited log visibility

- RS62552 - Fixed database authentication failures for LDAP users when the password contains the `%` character

title: Breaking changes

text:
- Differences when using the `UNWATCH` command within a `MULTI` command sequence:

    - Redis Enterprise: `UNWATCH` is not allowed within a `MULTI` command sequence and returns an error.

    - OSS: `UNWATCH` is allowed within a `MULTI` sequence but has no effect.

- When sending a `PUBSUB SHARDNUMSUB` command in OSS Cluster mode in Redis Enterprise, Redis Enterprise checks the hash slots of the requested channels. Redis Enterprise responds with a `CROSSSLOT` error if the channels don’t hash to the same slot, or a `MOVED` error if the channels hash to a different node.

#### Client prerequisites for Redis 7.2 upgrade

The Redis clients [Go-Redis](https://redis.uptrace.dev/) version 9 and [Lettuce](https://redis.github.io/lettuce/) versions 6 and later use RESP3 by default. If you use either client to run Redis Stack commands, you should set the client's protocol version to RESP2 before upgrading your database to Redis version 7.2 to prevent potential application issues due to RESP3 breaking changes.

For applications using Go-Redis v9.0.5 or later, set the protocol version to RESP2:

[code example]

To set the protocol version to RESP2 with Lettuce v6 or later:

[code example]

If you are using [LettuceMod](https://github.com/redis-developer/lettucemod/), you need to upgrade to [v3.6.0](https://github.com/redis-developer/lettucemod/releases/tag/v3.6.0).

title: Upcoming changes

text:
#### Prepare for restrictive pub/sub permissions

Redis database version 6.2 introduced pub/sub ACL rules that determine which [pub/sub channels]() a user can access.

The configuration option `acl-pubsub-default`, added in Redis Enterprise Software version 6.4.2, determines the cluster-wide default level of access for all pub/sub channels. Redis Enterprise Software uses the following pub/sub permissions by default:

- For versions 6.4.2 and 7.2, `acl-pubsub-default` is permissive (`allchannels` or `&*`) by default to accommodate earlier Redis versions.

- In future versions, `acl-pubsub-default` will change to restrictive (`resetchannels`). Restrictive permissions block all pub/sub channels by default, unless explicitly permitted by an ACL rule.

If you use ACLs and pub/sub channels, you should review your databases and ACL settings and plan to transition your cluster to restrictive pub/sub permissions in preparation for future Redis Enterprise Software releases.

When you change the cluster's default pub/sub permissions to restrictive, `&*` is added to the **Full Access** ACL. Before you make this change, consider the following:

- Because pub/sub ACL syntax was added in Redis 6.2, you can't associate the **Full Access** ACL with database versions 6.0 or lower after this change.

- The **Full Access** ACL is not reverted if you change `acl-pubsub-default` to permissive again.

- Every database with the default user enabled uses the **Full Access** ACL.

To secure pub/sub channels and prepare your cluster for future Redis Enterprise Software releases that default to restrictive pub/sub permissions:

1. Upgrade Redis databases:

    - For Redis Enterprise Software version 6.4.2, upgrade all databases in the cluster to Redis DB version 6.2.

    - For Redis Enterprise Software version 7.2.4, upgrade all databases in the cluster to Redis DB version 7.2 or 6.2.

1. Create or update ACLs with permissions for specific channels using the `resetchannels &channel` format.

1. Associate the ACLs with relevant databases.

1. Set default pub/sub permissions (`acl-pubsub-default`) to restrictive. See [Change default pub/sub permissions](#change-default-pubsub-permissions) for details.

1. If any issues occur, you can temporarily change the default pub/sub setting back to permissive. Resolve any problematic ACLs before making pub/sub permissions restrictive again.

#### Upcoming command request and reponse changes

Open source Redis version 7.2 changes the request and response policies for several commands. Because the GA release of Redis Enterprise version 7.2 does not include these policy changes, commands might behave differently from open source Redis. However, these changes will be included in a future Redis Enterprise maintenance release:

- [`RANDOMKEY`]() and [`SCAN`]() will change from no response policy to a `SPECIAL` response policy.

- [`MSETNX`]() currently has a `MULTI_SHARD` request policy and `AGG_MIN` response policy. Both will change to no policy.

For more information about request and response policies, see [Redis command tips]().

title: Known issues

text:
#### Legacy UI known issues

When using the legacy UI, you cannot update and save your changes on the **settings > preferences** tab even though these settings are visible. This issue will be fixed in the next maintenance release.

As a workaround, use the new Cluster Manager UI to update these settings from the **Cluster > Security > Preferences** tab.

#### Pub/sub channel ACL limitations

In Redis Enterprise Software version 6.4.2, you could use `&channel` syntax in Redis ACL rules to allow access to specific pub/sub channels even when default pub/sub permissions were permissive (`&allchannels` or `&*`), allowing all channels by default. However, `&allchannels &channel` is not valid syntax.

As of Redis Enterprise Software version 7.2.4, you cannot create Redis ACLs with this combination of rules. You can only use `&channel` to allow access to specific channels if the default pub/sub permissions are restrictive (`resetchannels`).

Associating an ACL that contains the invalid syntax <nobr>`&allchannels &channel`</nobr> (created before version 7.2) with a user and database might leave the database in a pending state, unable to function.

To prevent this issue:

1. Review all existing ACL rules.

1. For each rule containing `&channel`, either:

    - Add the `resetchannels` prefix to restrict access to all channels by default.

    - Delete the rule if not needed.

title: Known limitations

text:
#### Command limitations

- [`CLIENT NO-TOUCH`]() might not run correctly in the following cases:

    - The Redis database version is earlier than 7.2.0.

    - The `CLIENT NO-TOUCH` command is forbidden by ACL rules.

    Before sending this command, clients should verify the database version is 7.2.0 or later and that using this command is allowed.

- You cannot use [`SUNSUBSCRIBE`]() to unsubscribe from a shard channel if the regex changed while subscribed.

- Using [`XREADGROUP BLOCK`]() with `>` to return all new streams will cause the Redis database to freeze until the shard is restarted. ([#12031](https://github.com/redis/redis/pull/12301))

- Because a rejected command does not record the duration for command stats, an error will appear after it is reprocessed that will cause the Redis database to freeze until the shard is restarted. ([#12247](https://github.com/redis/redis/pull/12247))

#### Modules cannot load in Oracle Linux 7 & 8

Databases hosted on Oracle Linux 7 & 8 cannot load modules.

As a temporary workaround, you can change the node's `os_name` in the Cluster Configuration Store (CCS):

[code example]

#### Cluster recovery with manually uploaded modules

For clusters containing databases with manually uploaded modules, [cluster recovery]() requires an extra step.

After installing Redis Enterprise Software on the cluster nodes, upload compatible modules to `modulesdir` (`/opt/redislabs/lib/modules`) before continuing the recovery process.

This limitation will be removed in a future maintenance release.

#### Open source Redis security fixes compatibility

As part of Redis's commitment to security, Redis Enterprise Software implements the latest [security fixes](https://github.com/redis/redis/releases) available with [open source Redis](https://github.com/redis/redis). Redis Enterprise has already included the fixes for the relevant CVEs.

Some CVEs announced for open source Redis do not affect Redis Enterprise due to different or additional functionality available in Redis Enterprise that is not available in open source Redis.

Redis Enterprise 7.2.4-52 supports open source Redis 7.2, 6.2, and 6.0. Below is the list of open source Redis CVEs fixed by version.

Redis 7.2.0 includes all of the CVE fixes from previous versions.

- (CVE-2021-32625) An integer overflow bug in Redis version 6.0 or newer can be exploited using the STRALGO LCS command to corrupt the heap and potentially result with remote code execution. This is a result of an incomplete fix by CVE-2021-29477. (Redis 6.2.4)

- (CVE-2021-29478) An integer overflow bug in Redis 6.2 could be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves changing the default set-max-intset-entries configuration value, creating a large set key that consists of integer values and using the COPY command to duplicate it. The integer overflow bug exists in all versions of Redis starting with 2.6, where it could result with a corrupted RDB or DUMP payload, but not exploited through COPY (which did not exist before 6.2). (Redis 6.2.3)

#### Open source Redis security fixes compatibility

As part of Redis's commitment to security, Redis Enterprise Software implements the latest [security fixes](https://github.com/redis/redis/releases) available with [open source Redis](https://github.com/redis/redis). Redis Enterprise has already included the fixes for the relevant CVEs.

Some CVEs announced for open source Redis do not affect Redis Enterprise due to different or additional functionality available in Redis Enterprise that is not available in open source Redis.

Redis Enterprise 7.2.4-64 supports open source Redis 7.2, 6.2, and 6.0. Below is the list of open source Redis CVEs fixed by version.

Redis 7.2.x:

- (CVE-2023-41056) In some cases, Redis may incorrectly handle resizing of memory buffers, which can result in incorrect accounting of buffer sizes and lead to heap overflow and potential remote code execution.

- (CVE-2023-41053) Redis does not correctly identify keys accessed by `SORT_RO` and, as a result, may grant users executing this command access to keys that are not explicitly authorized by the ACL configuration. (Redis 7.2.1)

Redis 7.0.x:

- (CVE-2023-41056) In some cases, Redis may incorrectly handle resizing of memory buffers, which can result in incorrect accounting of buffer sizes and lead to heap overflow and potential remote code execution.

- (CVE-2023-41053) Redis does not correctly identify keys accessed by `SORT_RO` and, as a result, may grant users executing this command access to keys that are not explicitly authorized by the ACL configuration. (Redis 7.0.13)

- (CVE-2023-36824) Extracting key names from a command and a list of arguments may, in some cases, trigger a heap overflow and result in reading random heap memory, heap corruption, and potentially remote code execution. Specifically: using `COMMAND GETKEYS*` and validation of key names in ACL rules. (Redis 7.0.12)

- (CVE-2023-28856) Authenticated users can use the `HINCRBYFLOAT` command to create an invalid hash field that will crash Redis on access. (Redis 7.0.11)

The problem affects Redis versions 7.0.0 or newer. (Redis 7.0.5)

- (CVE-2022-31144) A specially crafted `XAUTOCLAIM` command on a stream key in a specific state may result in heap overflow and potentially remote code execution. The problem affects Redis versions 7.0.0 or newer. (Redis 7.0.4)

- (CVE-2022-24834) A specially crafted Lua script executing in Redis can trigger a heap overflow in the cjson and cmsgpack libraries, and result in heap corruption and potentially remote code execution. The problem exists in all versions of Redis with Lua scripting support, starting from 2.6, and affects only authenticated and authorized users. (Redis 7.0.12)

- (CVE-2022-24736) An attacker attempting to load a specially crafted Lua script can cause NULL pointer dereference which will result in a crash of the `redis-server` process. This issue affects all versions of Redis. (Redis 7.0.0)

- (CVE-2022-24735) By exploiting weaknesses in the Lua script execution environment, an attacker with access to Redis can inject Lua code that will execute with the (potentially higher) privileges of another Redis user. (Redis 7.0.0)

Redis 6.2.x:

- (CVE-2023-28856) Authenticated users can use the `HINCRBYFLOAT` command to create an invalid hash field that will crash Redis on access. (Redis 6.2.12)

- (CVE-2021-32625) An integer overflow bug in Redis version 6.0 or newer can be exploited using the STRALGO LCS command to corrupt the heap and potentially result with remote code execution. This is a result of an incomplete fix by CVE-2021-29477. (Redis 6.2.4)

- (CVE-2021-29478) An integer overflow bug in Redis 6.2 could be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves changing the default set-max-intset-entries configuration value, creating a large set key that consists of integer values and using the COPY command to duplicate it. The integer overflow bug exists in all versions of Redis starting with 2.6, where it could result with a corrupted RDB or DUMP payload, but not exploited through COPY (which did not exist before 6.2). (Redis 6.2.3)

- (CVE-2021-29477) An integer overflow bug in Redis version 6.0 or newer could be exploited using the STRALGO LCS command to corrupt the heap and potentially result in remote code execution. The integer overflow bug exists in all versions of Redis starting with 6.0. (Redis 6.2.3)

#### Open source Redis security fixes compatibility

As part of Redis's commitment to security, Redis Enterprise Software implements the latest [security fixes](https://github.com/redis/redis/releases) available with [open source Redis](https://github.com/redis/redis). Redis Enterprise has already included the fixes for the relevant CVEs.

Some CVEs announced for open source Redis do not affect Redis Enterprise due to different or additional functionality available in Redis Enterprise that is not available in open source Redis.

Redis Enterprise 7.2.4-92 and 7.2.4-86 support open source Redis 7.2, 6.2, and 6.0. Below is the list of open source Redis CVEs fixed by version.

Redis 7.2.x:

- (CVE-2023-41056) In some cases, Redis may incorrectly handle resizing of memory buffers, which can result in incorrect accounting of buffer sizes and lead to heap overflow and potential remote code execution.

- (CVE-2023-41053) Redis does not correctly identify keys accessed by `SORT_RO` and, as a result, may grant users executing this command access to keys that are not explicitly authorized by the ACL configuration. (Redis 7.2.1)

Redis 7.0.x:

- (CVE-2023-41056) In some cases, Redis may incorrectly handle resizing of memory buffers, which can result in incorrect accounting of buffer sizes and lead to heap overflow and potential remote code execution.
