<description>
<p>
Zero Day Initiative (ZDI) reported a heap buffer overflow
vulnerability. The vulnerability is due to an incorrect boundary check
of the user-supplied data prior to copying it to an insufficiently
sized memory buffer. The flaw occurs when the application attempts to
handle compressed UPX files.
</p>
</description>
<impact type="high">
<p>
For example by sending a maliciously crafted UPX file into a mail
server that is integrated with ClamAV, a remote attacker's supplied
code could be executed with escalated privileges.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All ClamAV users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-antivirus/clamav-0.88&quot;</code>
</resolution>
