Debian LTS Advisory DLA-3624-1 [email protected]
https://www.debian.org/lts/security/ Chris Lamb

Package : zookeeper
Version : 3.4.13-2+deb10u1
CVE ID : CVE-2023-44981
Debian Bug : 1054224
It was discovered that there was a potential authorisation bypass
vulnerability in Apache Zookeeper, a co-ordination service for
reliable distributed applications.
Specifically, if SASL Quorum Peer authentication was enabled via
quorum.auth.enableSasl, authorisation was performed by verifying that
the instance part in the SASL authentication ID was listed in the
zoo.cfg server list. However, this value is optional, and, if missing
(such as in '[email protected]'), the authorisation check will be
skipped. As a result, an arbitrary endpoint could join the cluster
and begin propagating counterfeit changes to the leader, essentially
giving it complete read-write access to the data tree.
For Debian 10 buster, this problem has been fixed in version
3.4.13-2+deb10u1.
We recommend that you upgrade your zookeeper packages.
For the detailed security status of zookeeper please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/zookeeper
