<title>teTeX, pTeX, CSTeX: Multiple overflows in included XPdf code</title>
<synopsis>
CSTeTeX, pTeX, and teTeX include vulnerable XPdf code to handle PDF files,
making them vulnerable to the execution of arbitrary code.

<p>
teTex is a complete TeX distribution. It is used for creating and
manipulating LaTeX documents. CSTeX is a TeX distribution with Czech
and Slovak support. pTeX is and ASCII publishing TeX distribution.
</p>

<description>
<p>
CSTeX, teTex, and pTeX include XPdf code to handle PDF files. This
XPdf code is vulnerable to several heap overflows (GLSA 200512-08) as
well as several buffer and integer overflows discovered by Chris Evans
(CESA-2005-003).
</p>
</description>
<impact type="normal">
<p>
An attacker could entice a user to open a specially crafted PDF
file with teTeX, pTeX or CSTeX, potentially resulting in the execution
of arbitrary code with the rights of the user running the affected
application.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All teTex users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/tetex-2.0.2-r8"</code>
<p>
All CSTeX users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/cstetex-2.0.2-r2"</code>
<p>
All pTeX users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/ptex-3.1.5-r1"</code>
