- ------------------------------------------------------------------------- Debian LTS Advisory DLA-4240-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb July 12, 2025 https://wiki.debian.org/LTS

Package : redis Version : 5:6.0.16-1+deb11u7 CVE IDs : CVE-2025-32023 CVE-2025-48367 Debian Bugs : 1108975 1108981

Two issues were discovered in Redis, the key-value database:

* CVE-2025-32023: An authenticated user may have used a specially-crafted string to trigger a stack/heap out-of-bounds write during hyperloglog operations, potentially leading to a remote code execution vulnerability. Installations that used Redis' ACL system to restrict hyperloglog HLL commands are unaffected by this issue.

* CVE-2025-48367: An unauthenticated connection could have caused repeated IP protocol errors, leading to client starvation and ultimately become a Denial of Service (DoS) attack.

For Debian 11 bullseye, these problems have been fixed in version 5:6.0.16-1+deb11u7.

We recommend that you upgrade your redis packages.

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the redis packages.
