RHSA-2025:0693 - Security Advisory

Topic

An update for redis is now available for Red Hat Enterprise Linux 9.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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: 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)
