Debian 10: DLA-3627-1 Critical Redis Authentication Bypass Issue

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.
