+ <title>CSTeX: Multiple vulnerabilities</title>
+ <synopsis>
+ Multiple vulnerabilities were discovered in CSTeX, possibly allowing to
+ execute arbitrary code or overwrite arbitrary files.

+ <p>
+ CSTeX is a TeX distribution with Czech and Slovak support. It is used
+ for creating and manipulating LaTeX documents.
+ </p>
+ </background>
+ <description>
+ <p>
+ Multiple issues were found in the teTeX 2 codebase that CSTeX builds
+ upon (GLSA 200709-17, GLSA 200711-26). CSTeX also includes vulnerable
+ code from the GD library (GLSA 200708-05), from Xpdf (GLSA 200709-12,
+ GLSA 200711-22) and from T1Lib (GLSA 200710-12).
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ Remote attackers could possibly execute arbitrary code and local
+ attackers could possibly overwrite arbitrary files with the privileges
+ of the user running CSTeX via multiple vectors.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ CSTeX is not maintained upstream, so the package was masked in Portage.
+ We recommend that users unmerge CSTeX:
+ </p>
+ <code>
+ # emerge --unmerge app-text/cstetex</code>
+ <p>
+ As an alternative, users should upgrade their systems to use teTeX or
+ TeX Live with its Babel packages.
+ </p>
