<description>
<p>
Jean-Sebastien Guay-Leroux discovered a boundary error in the
fullpath() function in misc.c when processing overly long file and
directory names in ZOO archives.
</p>
</description>
<impact type="normal">
<p>
An attacker could craft a malicious ZOO archive and entice someone
to open it using zoo. This would trigger a stack-based buffer overflow
and potentially allow execution of arbitrary code with the rights of
the victim user.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All zoo users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-arch/zoo-2.10-r1&quot;</code>
</resolution>
