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 6.4.2-110 supports open source Redis 6.2 and 6.0. Below is the list of open source Redis CVEs fixed by version.
Redis 6.2.x:
-
(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
, andHRANDFIELD
commands can trigger an integer overflow, resulting in a runtime assertion and termination of the Redis server process. (Redis 6.2.11) -
(CVE-2023-22458) Integer overflow in the Redis
HRANDFIELD
andZRANDMEMBER
commands can lead to denial-of-service. (Redis 6.2.9) -
(CVE-2022-36021) String matching commands (like
SCAN
orKEYS
) with a specially crafted pattern to trigger a denial-of-service attack on Redis, causing it to hang and consume 100% CPU time. (Redis 6.2.11) -
(CVE-2022-35977) Integer overflow in the Redis
SETRANGE
andSORT
/SORT_RO
commands can drive Redis to OOM panic. (Redis 6.2.9) -
(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 6.2.13)
-
(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 6.2.7) -
(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
andredis-sentinel
parsing large multi-bulk replies on some older and less common platforms. (Redis 6.2.6) -
(CVE-2021-32761) An integer overflow bug in Redis version 2.2 or newer can be exploited using the
BITFIELD
command to corrupt the heap and potentially result with remote code execution. (Redis 6.2.5) -
(CVE-2021-32687) Integer to heap buffer overflow with intsets, when
set-max-intset-entries
is manually configured to a non-default, very large value. (Redis 6.2.6) -
(CVE-2021-32675) Denial Of Service when processing RESP request payloads with a large number of elements on many connections. (Redis 6.2.6)
-
(CVE-2021-32672) Random heap reading issue with Lua Debugger. (Redis 6.2.6)
-
(CVE-2021-32628) Integer to heap buffer overflow handling ziplist-encoded data types, when configuring a large, non-default value for
hash-max-ziplist-entries
,hash-max-ziplist-value
,zset-max-ziplist-entries
orzset-max-ziplist-value
. (Redis 6.2.6) -
(CVE-2021-32627) Integer to heap buffer overflow issue with streams, when configuring a non-default, large value for
proto-max-bulk-len
andclient-query-buffer-limit
. (Redis 6.2.6) -
(CVE-2021-32626) Specially crafted Lua scripts may result with Heap buffer overflow. (Redis 6.2.6)
-
(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)
Redis 6.0.x:
-
(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 6.0.20)
-
(CVE-2023-28856) Authenticated users can use the
HINCRBYFLOAT
command to create an invalid hash field that will crash Redis on access. (Redis 6.0.19) -
(CVE-2023-25155) Specially crafted
SRANDMEMBER
,ZRANDMEMBER
, andHRANDFIELD
commands can trigger an integer overflow, resulting in a runtime assertion and termination of the Redis server process. (Redis 6.0.18) -
(CVE-2022-36021) String matching commands (like
SCAN
orKEYS
) with a specially crafted pattern to trigger a denial-of-service attack on Redis, causing it to hang and consume 100% CPU time. (Redis 6.0.18) -
(CVE-2022-35977) Integer overflow in the Redis
SETRANGE
andSORT
/SORT_RO
commands can drive Redis to OOM panic. (Redis 6.0.17)
