Samba NMBD Logon Request Remote Buffer Overflow Vulnerability
Samba is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data.
This issue occurs only when Samba is configured as a Primary or Backup Domain Controller.
Attackers can exploit this issue to cause denial-of-service conditions. Given the nature of this issue, attackers may also be able to execute remote code, but the vendor doesn't think that this is possible.
Samba 3.0.0 through 3.0.26a are vulnerable.
