<p>
CSTeX is a TeX distribution with Czech and Slovak support. It is used
for creating and manipulating LaTeX documents.

<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).

</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.
