Synopsis
========

Multiple buffer overflows in OpenTTD might allow for the execution of
arbitrary code in the server.

Background
==========

OpenTTD is a clone of Transport Tycoon Deluxe.

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

    -------------------------------------------------------------------
     Package                   /  Vulnerable  /             Unaffected
    -------------------------------------------------------------------
  1  games-simulation/openttd       < 0.6.3                   >= 0.6.3

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

Multiple buffer overflows have been reported in OpenTTD, when storing
long for client names (CVE-2008-3547), in the TruncateString function
in src/gfx.cpp (CVE-2008-3576) and in src/openttd.cpp when processing a
large filename supplied to the "-g" parameter in the ttd_main function
(CVE-2008-3577).

Impact
======

An authenticated attacker could exploit these vulnerabilities to
execute arbitrary code with the privileges of the OpenTTD server.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All OpenTTD users should upgrade to the latest version:

    # emerge --sync
    # 
emerge --ask --oneshot --verbose ">=games-simulation/openttd-0.6.3"
