Synopsis
========

Samba contains a bug that could lead to remote execution of arbitrary
code.

Background
==========

Samba is a freely available SMB/CIFS implementation which allows
seamless interoperability of file and print services to other SMB/CIFS
clients.

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

    -------------------------------------------------------------------
     Package       /  Vulnerable  /                         Unaffected
    -------------------------------------------------------------------
  1  net-fs/samba      <= 3.0.9                            >= 3.0.9-r1

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

Samba contains a bug when unmarshalling specific MS-RPC requests from
clients.

Impact
======

A remote attacker may be able to execute arbitrary code with the
permissions of the user running Samba, which could be the root user.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All samba users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.9-r1"
