Summary
Gentoo Linux Security Advisory GLSA 200805-07
https://security.gentoo.org/
Severity: Normal
Title: Linux Terminal Server Project: Multiple vulnerabilities
Date: May 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
-------------------------------------------------------------------
1 net-misc/ltsp < 5.0 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.
==========
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.
