The remote host is missing updates announced in advisory GLSA 200711-34.

CSTeX is not maintained upstream, so the package was masked in Portage. We recommend that users unmerge CSTeX: # emerge --unmerge app-text/cstetex As an alternative, users should upgrade their systems to use teTeX or TeX Live with its Babel packages. http://www.securityspace.com/smysecure/catid.html?in=GLSA%20200711-34 http://bugs.gentoo.org/show_bug.cgi?id=196673 http://www.gentoo.org/security/en/glsa/glsa-200708-05.xml http://www.gentoo.org/security/en/glsa/glsa-200709-12.xml http://www.gentoo.org/security/en/glsa/glsa-200709-17.xml http://www.gentoo.org/security/en/glsa/glsa-200710-12.xml http://www.gentoo.org/security/en/glsa/glsa-200711-22.xml http://www.gentoo.org/security/en/glsa/glsa-200711-26.xml
