CVE-2021-23192  (opens in a new tab)

How to fix?

Upgrade SLES:15.2 samba-ad-dc to version 4.11.14+git.308.666c63d4eea-4.28.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream samba-ad-dc package and not the samba-ad-dc package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

A flaw was found in the way samba implemented DCE/RPC. If a client to a Samba server sent a very large DCE/RPC request, and chose to fragment it, an attacker could replace later fragments with their own data, bypassing the signature requirements.
