CVE-2022-24834

Redis is an in-memory database that persists on disk. A specially crafted Lua script executing in Redis can trigger a heap overflow in the cjson library, and result with 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. The problem is fixed in versions 7.0.12, 6.2.13, and 6.0.20.

Redis is an advanced key-value store. It is often referred to as a data-structure server since keys can contain strings, hashes, lists, sets, and sorted sets. For performance, Redis works with an in-memory data set. You can persist it either by dumping the data set to disk every once in a while, or by appending each command to a log.

Security Fix(es):

• redis: Integer overflow in the Redis HRANDFIELD and ZRANDMEMBER commands may lead to denial-of-service (CVE-2023-22458)

• redis: Integer overflow in the Redis SETRANGE and SORT/SORT_RO commands may result with false OOM panic (CVE-2022-35977)

• redis: Specially crafted SRANDMEMBER, ZRANDMEMBER, and HRANDFIELD commands can trigger an integer overflow (CVE-2022-36021)

• redis: String matching commands (like SCAN or KEYS) with a specially crafted pattern to trigger a denial-of-service attack (CVE-2023-25155)

• redis: Insufficient validation of HINCRBYFLOAT command (CVE-2023-28856)

• redis: heap overflow in the lua cjson and cmsgpack libraries (CVE-2022-24834)

• redis: possible bypass of Unix socket permissions on startup (CVE-2023-45145)

• redis: Lua library commands may lead to stack overflow and RCE in Redis (CVE-2024-31449)

• redis: Denial-of-service due to unbounded pattern matching in Redis (CVE-2024-31228)

• redis: Redis' Lua library commands may lead to remote code execution (CVE-2024-46981)
