Linux Terminal Server Project: Multiple vulnerabilities — GLSA 200805-07

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

Affected packages

net-misc/ltsp on all architectures
Affected versions < 5.0
Unaffected versions


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


LTSP version 4.2, ships prebuilt copies of programs such as the Linux Kernel, the 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.


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.


There is no known workaround at this time.


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.
