CBL Mariner 2.0 Security Update: redis (CVE-2025-32023)

high Nessus Plugin ID 242018

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of redis installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-32023 advisory.

 - Redis is an open source, in-memory database that persists on disk. From 2.8 to before 8.0.3, 7.4.5, 7.2.10, and 6.2.19, an authenticated user May use a specially crafted string to trigger a stack/heap out of bounds write on hyperloglog operations, potentially leading to remote code execution. The bug likely affects all Redis versions with hyperloglog operations implemented. This vulnerability is fixed in 8.0.3, 7.4.5, 7.2.10, and 6.2.19. An additional workaround to mitigate the problem without patching the redis- server executable is to prevent users from executing hyperloglog operations. This can be done using ACL to restrict HLL commands. (CVE-2025-32023)

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

Solution

Update the affected packages.
