<title>teTeX, pTeX, CSTeX: Multiple vulnerabilities</title>
|
|
<synopsis>
|
|
teTeX, pTeX and CSTeX make use of vulnerable Xpdf code which may allow the
|
|
remote execution of arbitrary code. Furthermore, the xdvizilla script is
|
|
vulnerable to temporary file handling issues.

teTeX is a complete and open source TeX distribution. CSTeX is
|
|
another TeX distribution including Czech and Slovak support. pTeX is
|
|
another alternative that allows Japanese publishing with TeX. xdvizilla
|
|
is an auxiliary script used to integrate DVI file viewing in
|
|
Mozilla-based browsers.

teTeX, pTeX and CSTeX all make use of Xpdf code and may therefore
|
|
be vulnerable to the various overflows that were discovered in Xpdf
|
|
code (CAN-2004-0888, CAN-2004-0889, CAN-2004-1125 and CAN-2005-0064).
|
|
Furthermore, Javier Fernandez-Sanguino Pena discovered that the
|
|
xdvizilla script does not handle temporary files correctly.

<impact type="normal">
|
|
<p>
|
|
An attacker could design a malicious input file which, when
|
|
processed using one of the TeX distributions, could lead to the
|
|
execution of arbitrary code. Furthermore, a local attacker could create
|
|
symbolic links in the temporary files directory, pointing to a valid
|
|
file somewhere on the filesystem. When xdvizilla is called, this would
|
|
result in the file being overwritten with the rights of the user
|
|
running the script.

All teTeX users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/tetex-2.0.2-r5"</code>
|
|
<p>
|
|
All CSTeX users should also upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/cstetex-2.0.2-r1"</code>
|
|
<p>
|
|
Finally, all pTeX users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/ptex-3.1.4-r2"</code>
