"The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by a vulnerability
as referenced in the SUSE-SU-2023:4290-1 advisory.
- Redis is an in-memory database that persists on disk. On startup, Redis begins listening on a Unix socket
before adjusting its permissions to the user-provided configuration. If a permissive umask(2) is used,
this creates a race condition that enables, during a short period of time, another process to establish an
otherwise unauthorized connection. This problem has existed since Redis 2.6.0-RC1. This issue has been
addressed in Redis versions 7.2.2, 7.0.14 and 6.2.14. Users are advised to upgrade. For users unable to
upgrade, it is possible to work around the problem by disabling Unix sockets, starting Redis with a
restrictive umask, or storing the Unix socket file in a protected directory. (CVE-2023-45145)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
