Debian 11 and 12: DSA-5544-1 Moderate: Zookeeper Authentication Issue

Damien Diederen discovered that SASL quorum peer authentication within
Zookeeper, a service for maintaining configuration information, was
insufficiently enforced in some configurations.

For the oldstable distribution (bullseye), this problem has been fixed
in version 3.4.13-6+deb11u1.

For the stable distribution (bookworm), this problem has been fixed in
version 3.8.0-11+deb12u1.

We recommend that you upgrade your zookeeper packages.

For the detailed security status of zookeeper please refer to
