Synopsis
========

Gaim contains several security issues that might allow an attacker to
execute arbitrary code or commands.

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-r5                             >= 0.81-r5

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

Gaim fails to do proper bounds checking when:

* Handling MSN messages (partially fixed with GLSA 200408-12).

* Handling rich text format messages.

* Resolving local hostname.

* Receiving long URLs.

* Handling groupware messages.

* Allocating memory for webpages with fake content-length header.

Furthermore Gaim fails to escape filenames when using drag and drop
installation of smiley themes.

Impact
======

These vulnerabilites could allow an attacker to crash Gaim or execute
arbitrary code or commands 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-r5"
    # emerge ">=net-im/gaim-0.81-r5"
