 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-4325-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb October 09, 2025 https://wiki.debian.org/LTS

 Package : redis Version : 5:6.0.16-1+deb11u8 CVE IDs : CVE-2025-46817 CVE-2025-46819 CVE-2025-49844 Debian Bug : 1117553

 Multiple vulnerabilities were discovered in Redis, a popular key/value database:

 * CVE-2025-46817: Fix an issue where an authenticated user could have used a specially-crafted Lua script to cause an integer overflow and potentially lead to remote code execution.

 * CVE-2025-46819: Address a potential vulnerability where an authenticated user could have used a specially-crafted Lua script to read out-of-bound data and/or crash the server and thereby create a denial of service attack.

 * CVE-2025-49844: Fix an issue where authenticated users could have exploited a specially-crafted Lua script to manipulate the garbage collector, trigger a use-after-free and potentially lead to remote code execution.

 For Debian 11 bullseye, these problems have been fixed in version 5:6.0.16-1+deb11u8.

 We recommend that you upgrade your redis packages.
