Synopsis
========

Multiple vulnerabilities have been found in Gaim which could allow a
remote attacker to crash the application.

Background
==========

Gaim is a full featured instant messaging client which handles a
variety of instant messaging protocols.

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

    -------------------------------------------------------------------
     Package      /  Vulnerable  /                          Unaffected
    -------------------------------------------------------------------
  1  net-im/gaim       < 1.1.4                                >= 1.1.4

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

Specially crafted SNAC packets sent by other instant-messaging users
can cause Gaim to loop endlessly (CAN-2005-0472). Malformed HTML code
could lead to invalid memory accesses (CAN-2005-0208 and
CAN-2005-0473).

Impact
======

Remote attackers could exploit these issues, resulting in a Denial of
Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Gaim users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-im/gaim-1.1.4"
