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"
