Synopsis
========
OpenTTD is vulnerable to several format string vulnerabilities, which
may result in remote execution of arbitrary code.

Background
==========
OpenTTD is modeled after the original Transport Tycoon game by Chris
Sawyer and enhances the game experience dramatically. Many features were
inspired by TTDPatch while others are original.

Description
===========
CAN-2005-2763:
Multiple format string vulnerabilities in OpenTTD before 0.4.0.1 allow
remote attackers to cause a denial of service (crash) and possibly
execute arbitrary code via unspecified vectors.

Impact
======
A remote attacker could exploit these vulnerabilities to crash the
OpenTTD server or client and possibly execute arbitrary code with the
rights of the user running OpenTTD.

Workaround
==========
There are no known workarounds at this time.

Affected packages
=================
openttd in games grimoire is affected. This is now fixed in this grimoire.

Resolution
==========
All openttd users should upgrade to the latest available version:
         # scribe update
         # cast -c openttd
