Samba < 3.0.28 'send_mailslot' Function Buffer Overflow

critical Nessus Network Monitor Plugin ID 4311

Synopsis

The remote Samba server may be affected by a buffer overflow vulnerability.

Description

According to its banner, the version of the Samba server on the remote host is reportedly affected by a boundary error in 'nmbd' within the 'send_mailslot' function. Provided the 'domain logons' option is enabled in 'smb.conf', an attacker can leverage this issue to produce a stack-based buffer overflow using a 'SAMLOGON' domain logon packet in which the username string is placed at an odd offset and is followed by a long 'GETDC' string. Note that NNM has not verified whether 'domain logons' are enabled on the remote host.

Solution

Upgrade to version 3.0.28 or higher.
