CVE-2019-14833

Priority
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.
