Summary
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)

High 7.0
Heap overflow issue with the Lua cjson library used by Redis
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…

High 7.0CVE-2024-31449 Public exploit
Lua library commands may lead to stack overflow and RCE in Redis
Redis is an open source, in-memory database that persists on disk. 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. The problem exists in a…

High 7.0CVE-2024-46981 Public exploit
Redis' Lua library commands may lead to remote code execution
Redis is an open source, in-memory database that persists on disk. An authenticated user may use a specially crafted Lua script to manipulate the garbage collector and potentially lead to remote code execution. The problem is fixed in 7.4.2, 7.2.7, and 6.2.17…

Medium 5.5CVE-2022-35977 EPSS 14%
Integer overflow in certain command arguments can drive Redis to OOM panic
Redis is an in-memory database that persists on disk. Authenticated users issuing specially crafted `SETRANGE` and `SORT(_RO)` commands can trigger an integer overflow, resulting with Redis attempting to allocate impossible amounts of memory and abort with an…

Medium 5.5CVE-2022-36021 EPSS 60%
Redis string pattern matching can be abused to achieve Denial of Service
Redis is an in-memory database that persists on disk. Authenticated users can use 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. T…

Medium 5.5CVE-2023-22458 EPSS 72%
Integer overflow in multiple Redis commands can lead to denial-of-service
Redis is an in-memory database that persists on disk. Authenticated users can issue a `HRANDFIELD` or `ZRANDMEMBER` command with specially crafted arguments to trigger a denial-of-service by crashing Redis with an assertion failure. This problem affects Redis…
-
Medium 5.5
Integer Overflow in several Redis commands can lead to denial of service.
Redis is an in-memory database that persists on disk. Authenticated users issuing specially crafted `SRANDMEMBER`, `ZRANDMEMBER`, and `HRANDFIELD` commands can trigger an integer overflow, resulting in a runtime assertion and termination of the Redis server p…

Medium 5.5
`HINCRBYFLOAT` can be used to crash a redis-server process
Redis is an open source, in-memory database that persists on disk. Authenticated users can use the `HINCRBYFLOAT` command to create an invalid hash field that will crash Redis on access in affected versions. This issue has been addressed in in versions 7.0.11…

Medium 5.5
Denial-of-service due to unbounded pattern matching in Redis
Redis is an open source, in-memory database that persists on disk. Authenticated users 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…

Low 3.6
Redis Unix-domain socket may have be exposed with the wrong permissions for a short time window.
Redis is an in-memory database that persists on disk. On startup, Redis begins listening on a Unix socket before adjusting its permissions to the user-provided configuration. If a permissive umask(2) is used, this creates a race condition that enables, during…
