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 'e...@example.com'), 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 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEwv5L0nHBObhsUz5GHpU+J9QxHlgFAmUynL4ACgkQHpU+J9Qx HlgY3Q/9G3X0BuGXE9ea+j5amXtlcSe1XLexYt/DVAhaZRvKAYqhAI2eBPCzxwUm H72olieD/A0eSwtRKA1vZY8QCk7EpvIIk+5jKygJZ7cnrAEnl1YTtKDrclmpCIHS 4VYfCIiI1TaU4iw4XJ0GqDmkpuY14w/F2egS+Xvm355j3pNNVm/xsAAYAA/lh0IS qRaxHf93CacCERPSny9peNPWy6pxWLwH9YhF4nPFNpg5A4qqWXW+IBxYxESrwVyU NGFKcZeE0Mwe/3H9Q9XajQVex1/cIliGNxalqQt7R3au9XWPiE4es+Z4Xwivj3HU xk/dIiOTw4EkMgpFJIRov59P4JnathTFjFLr3Tedd5D6ziOGXQQ78t6Y8v+/H7jz GJlzd/Xdinu7FenlDOifwxdFJMhBM4byaEcP52EQrK5SOSwUkbQ7NYSEinSlbRuh bSigP+W+g8fzd+8x03CWBsa6BQQX1/V2Wd3aAfmT8jlpt3oT3FGyi5NCN+qOstIj BCLg2kOjxctuTu+yDELkTn9DVUIJnSVZbIlsDqR5m1LEqjEritdjlvGF6XPV+MPV skQQWQfpuqr6DKSCsfdbQLEIcHROwOjPhLa/Cbp0ViCbCJRHUhafQRToB2syXECE lGNgCXAzChZ60GTJt1YZTMdpC18kRTzijJQry2WdXZbyFfYYzXQ= =NT9r -----END PGP SIGNATURE-----
