Synopsis
========

Gaim contains a remotely exploitable buffer overflow vulnerability in
the MSN-protocol parsing code that may allow remote execution of
arbitrary code.

Background
==========

Gaim is a multi-protocol instant messaging client for Linux which
supports many instant messaging protocols.

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

    -------------------------------------------------------------------
     Package      /  Vulnerable  /                          Unaffected
    -------------------------------------------------------------------
  1  net-im/gaim       <= 0.81                              >= 0.81-r1

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

Sebastian Krahmer of the SuSE Security Team has discovered a remotely
exploitable buffer overflow vulnerability in the code handling MSN
protocol parsing.

Impact
======

By sending a carefully-crafted message, an attacker may execute
arbitrary code with the permissions of the user running Gaim.

Workaround
==========

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of Gaim.

Resolution
==========

All Gaim users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=net-im/gaim-0.81-r1"
    # emerge ">=net-im/gaim-0.81-r1"
