Description:

   This update for samba fixes the following issues:

   - CVE-2021-20251: Fixed an issue where the bad password count would not be

     user's password (bsc#1206546).
   - CVE-2022-37966: Fixed an issue where a weak cipher would be selected to
     encrypt session keys, which could lead to privilege escalation
     (bsc#1205385).
