Synopsis
========

The Quake 3 engine has a vulnerability that could be exploited to
execute arbitrary code.

Background
==========

Quake 3 is a multiplayer first person shooter.

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

    -------------------------------------------------------------------
     Package                    /  Vulnerable  /            Unaffected
    -------------------------------------------------------------------
  1  games-fps/quake3-bin            < 1.32c                  >= 1.32c
  2  games-fps/rtcw                  < 1.41b                  >= 1.41b
  3  games-fps/enemy-territory       < 2.60b                  >= 2.60b
    -------------------------------------------------------------------

    -------------------------------------------------------------------

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

landser discovered a vulnerability within the "remapShader" command.
Due to a boundary handling error in "remapShader", there is a
possibility of a buffer overflow.

Impact
======

An attacker could set up a malicious game server and entice users to
connect to it, potentially resulting in the execution of arbitrary code
with the rights of the game user.

Workaround
==========

Do not connect to untrusted game servers.

Resolution
==========

All Quake 3 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=games-fps/quake3-bin-1.32c"

All RTCW users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=games-fps/rtcw-1.41b"

All Enemy Territory users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=games-fps/enemy-territory-2.60b"
