Severity:	normal
Title:	Linux Terminal Server Project: Multiple vulnerabilities
Date:	05/09/2008
Bugs:	#215699
ID:	200805-07

Synopsis

Multiple vulnerabilities have been discovered in components shipped with LTSP which allow remote attackers to compromise terminal clients.

Background

The Linux Terminal Server Project adds thin-client support to Linux servers.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-misc/ltsp	< 5.0		All supported architectures

Description

LTSP version 4.2, ships prebuilt copies of programs such as the Linux Kernel, the X.org X11 server (GLSA 200705-06, GLSA 200710-16, GLSA 200801-09), libpng (GLSA 200705-24, GLSA 200711-08), Freetype (GLSA 200705-02, GLSA 200705-22) and OpenSSL (GLSA 200710-06, GLSA 200710-30) which were subject to multiple security vulnerabilities since 2006. Please note that the given list of vulnerabilities might not be exhaustive.

Impact

A remote attacker could possibly exploit vulnerabilities in the aforementioned programs and execute arbitrary code, disclose sensitive data or cause a Denial of Service within LTSP 4.2 clients.

Workaround

There is no known workaround at this time.

Resolution

LTSP 4.2 is not maintained upstream in favor of version 5. Since version 5 is not yet available in Gentoo, the package has been masked. We recommend that users unmerge LTSP:

    # emerge --unmerge net-misc/ltsp

If you have a requirement for Linux Terminal Servers, please either set up a terminal server by hand or use one of the distributions that already migrated to LTSP 5. If you want to contribute to the integration of LTSP 5 in Gentoo, or want to follow its development, find details in bug 177580.
