<p>
Two stack-based buffer overflows in the read_special_escape() function
in src/psgen.c have been reported. Ulf Harnhammar of Secunia Research
discovered a vulnerability related to the "setfilename" command
(CVE-2008-3863), and Kees Cook of Ubuntu discovered a vulnerability
related to the "font" escape sequence (CVE-2008-4306).
</p>
</description>
<impact type="normal">
<p>
An attacker could entice a user or automated system to process
specially crafted input with the special escapes processing enabled
using the "-e" option, possibly resulting in the execution of arbitrary
code.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All enscript users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-text/enscript-1.6.4-r4&quot;</code>
</resolution>
