CVE-2019-14833 Information

Description

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.
