NVD Description

Note: Versions mentioned in the description apply only to the upstream libsamba-util0-32bit package and not the libsamba-util0-32bit package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

A flaw was found in Samba, all versions starting samba 4.5.0 before samba 4.9.15, samba 4.10.10, samba 4.11.2, in the way it handles a user password change or a new password for a samba user. The Samba Active Directory Domain Controller can be configured to use a custom script to check for password complexity. This configuration can fail to verify password complexity when non-ASCII characters are used in the password, which could lead to weak passwords being set for samba users, making it vulnerable to dictionary attacks.
