Title:	Debian: Security Advisory (DLA-3627-1)
Summary:	The remote host is missing an update for the Debian 'redis' package(s) announced via the DLA-3627-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'redis' package(s) announced via the DLA-3627-1 advisory. Vulnerability Insight: It was discovered that there was a authentication bypass vulnerability in Redis, a popular key-value database similar to memcached. On startup, Redis began listening on a Unix socket before adjusting its permissions to the user-provided configuration. If a permissive umask(2) was used, this created a race condition that enabled, during a short period of time, another process to establish an otherwise unauthorized connection. CVE-2023-45145 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. For Debian 10 Buster, this problem has been fixed in version 5:5.0.14-1+deb10u5. We recommend that you upgrade your redis packages.

Solution: Please install the updated package(s). CVSS Score: 2.4 CVSS Vector: AV:L/AC:H/Au:S/C:P/I:P/A:N
