# CVE-2023-28856: redis: Redis is an advanced key-value store CVE-2023-28856 is fixed in 11 products on 1 platform, first by DEBIAN-CVE-2023-28856, released April 18, 2023. It is not reported as exploited. Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2023-28856 - Priority: High - CVSS: 7.0 (Important) - EPSS: 0.0126 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Apr 18, 2023 ## Description 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) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE
