Red Hat Security Advisory: redis security update
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: Lua library commands may lead to integer overflow and potential RCE (CVE-2025-46817) * Redis: Redis Lua Use-After-Free may lead to remote code execution (CVE-2025-49844) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
This advisory covers two vulnerabilities in Redis related to its Lua scripting capabilities. CVE-2025-46817 involves Lua library commands that may trigger an integer overflow, potentially allowing remote code execution. CVE-2025-49844 is a use-after-free vulnerability in Redis Lua that may also lead to remote code execution. Both vulnerabilities affect Redis as distributed in Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions. Red Hat has released updated Redis packages (version 6.2.7-1.el9_2.5) to fix these issues.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code remotely on affected systems running vulnerable Redis versions. This poses a high security risk as it may lead to full system compromise.
Mitigation Recommendations
Red Hat has released updated Redis packages that address these vulnerabilities. Users of Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions should apply the Redis update to version 6.2.7-1.el9_2.5 or later as provided by Red Hat. For detailed update instructions, refer to Red Hat's advisory and update documentation at https://access.redhat.com/articles/11258. Patch status is confirmed as fixed in these updated packages.
