<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).

<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.

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:
|

<code>
|

# emerge --sync
