Security

Open source Redis security fixes compatibility

As part of Redis's commitment to security, Redis Enterprise Software implements the latest security fixes available with open source 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 7.2.4-122 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-2024-31449) An authenticated user may use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may potentially lead to remote code execution.

  • (CVE-2024-31228) An authenticated user can trigger a denial-of-service by using specially crafted, long string match patterns on supported commands such as KEYS, SCAN, PSUBSCRIBE, FUNCTION LIST, COMMAND LIST, and ACL definitions. Matching of extremely long patterns may result in unbounded recursion, leading to stack overflow and process crashes.

  • (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-2024-31449) An authenticated user may use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may potentially lead to remote code execution.

  • (CVE-2024-31228) An authenticated user can trigger a denial-of-service by using specially crafted, long string match patterns on supported commands such as KEYS, SCAN, PSUBSCRIBE, FUNCTION LIST, COMMAND LIST, and ACL definitions. Matching of extremely long patterns may result in unbounded recursion, leading to stack overflow and process crashes.

  • (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)

  • (CVE-2023-28425) Specially crafted MSETNX command can lead to assertion and denial-of-service. (Redis 7.0.10)

  • (CVE-2023-25155) Specially crafted SRANDMEMBER, ZRANDMEMBER, and HRANDFIELD commands can trigger an integer overflow, resulting in a runtime assertion and termination of the Redis server process. (Redis 7.0.9)

  • (CVE-2023-22458) Integer overflow in the Redis HRANDFIELD and ZRANDMEMBER commands can lead to denial-of-service. (Redis 7.0.8)

  • (CVE-2022-36021) String matching commands (like SCAN or KEYS) with a specially crafted pattern to trigger a denial-of-service attack on Redis, causing it to hang and consume 100% CPU time. (Redis 7.0.9)

  • (CVE-2022-35977) Integer overflow in the Redis SETRANGE and SORT/SORT_RO commands can drive Redis to OOM panic. (Redis 7.0.8)

  • (CVE-2022-35951) Executing an XAUTOCLAIM command on a stream key in a specific state, with a specially crafted COUNT argument, may cause an integer overflow, a subsequent heap overflow, and potentially lead to remote code execution. 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-2024-31449) An authenticated user may use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may potentially lead to remote code execution.

  • (CVE-2024-31228) An authenticated user can trigger a denial-of-service by using specially crafted, long string match patterns on supported commands such as KEYS, SCAN, PSUBSCRIBE, FUNCTION LIST, COMMAND LIST, and ACL definitions. Matching of extremely long patterns may result in unbounded recursion, leading to stack overflow and process crashes.

  • (CVE-2023-45145) The wrong order of listen(2) and chmod(2) calls creates a race condition that can be used by another process to bypass desired Unix socket permissions on startup. (Redis 6.2.14)

  • (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-2023-25155) Specially crafted SRANDMEMBER, ZRANDMEMBER, and HRANDFIELD commands can trigger an integer overflow, resulting in a runtime assertion and termination of the Redis server process. (Redis 6.2.11)

  • (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 6.2.7)

  • (CVE-2021-41099) Integer to heap buffer overflow handling certain string commands and network payloads, when proto-max-bulk-len is manually configured to a non-default, very large value. (Redis 6.2.6)

  • (CVE-2021-32762) Integer to heap buffer overflow issue in redis-cli and redis-sentinel parsing large multi-bulk replies on some older and less common platforms. (Redis 6.2.6)

  • (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.
