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.

 

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.
