The remote host is missing updates announced in advisory GLSA 200805-07.

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. http://www.securityspace.com/smysecure/catid.html?in=GLSA%20200805-07 http://bugs.gentoo.org/show_bug.cgi?id=215699 http://www.gentoo.org/security/en/glsa/glsa-200705-02.xml http://www.gentoo.org/security/en/glsa/glsa-200705-06.xml http://www.gentoo.org/security/en/glsa/glsa-200705-22.xml http://www.gentoo.org/security/en/glsa/glsa-200705-24.xml http://www.gentoo.org/security/en/glsa/glsa-200710-06.xml http://www.gentoo.org/security/en/glsa/glsa-200710-16.xml http://www.gentoo.org/security/en/glsa/glsa-200710-30.xml http://www.gentoo.org/security/en/glsa/glsa-200711-08.xml http://www.gentoo.org/security/en/glsa/glsa-200801-09.xml https://bugs.gentoo.org/177580
