Synopsis
========

Samba contains a buffer overflow vulnerability potentially resulting in
the execution of arbitrary code.

Background
==========

Samba is a suite of SMB and CIFS client/server programs for UNIX.

Affected packages
=================

    -------------------------------------------------------------------
     Package       /  Vulnerable  /                         Unaffected
    -------------------------------------------------------------------
  1  net-fs/samba      < 3.0.28                              >= 3.0.28

Description
===========

Alin Rad Pop (Secunia Research) discovered a boundary checking error in
the send_mailslot() function which could lead to a stack-based buffer
overflow.

Impact
======

A remote attacker could send a specially crafted "SAMLOGON" domain
logon packet, possibly leading to the execution of arbitrary code with
elevated privileges. Note that this vulnerability is exploitable only
when domain logon support is enabled in Samba, which is not the case in
Gentoo's default configuration.

Workaround
==========

Disable domain logon in Samba by setting "domain logons = no" in the
"global" section of your smb.conf and restart Samba.

Resolution
==========

All Samba users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.28"

==========
