 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3627-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb October 23, 2023 https://wiki.debian.org/LTS

 Package : redis Version : 5:5.0.14-1+deb10u5 CVE ID : CVE-2023-45145 Debian Bug : 1054225

 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.

 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.

 For the detailed security status of redis please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/redis

Solution

Upgrade the redis packages.
