CVE [?]: CVE-2007-6015
CPE [?]: cpe:/a:samba:samba

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 Nessus has not actually tried to exploit this issue nor verify whether the 'domain logons' option has been enabled on the remote host.

Solution

Upgrade to Samba version 3.0.28 or later.
