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"
