Gentoo Linux Security Advisory

Title: OpenTTD: Execution of arbitrary code (GLSA 200903-09)
Severity: high
Exploitable: remote
Date: March 07, 2009
Bug(s): #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: games-simulation/openttd
Vulnerable: < 0.6.3
Unaffected: >= 0.6.3
Architectures: 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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=games-simulation/openttd-0.6.3"
