http://security.gentoo.org/

Severity:	high
Title:	OpenTTD: Execution of arbitrary code
Date:	03/07/2009
Bugs:	#233929
ID:	200903-09

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	Architecture(s)
games-simulation/openttd	< 0.6.3	>= 0.6.3	All supported architectures

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"
