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:
