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.
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.
