<p>
Clam AntiVirus (short: ClamAV) is an anti-virus toolkit for UNIX,
designed especially for e-mail scanning on mail gateways.
</p>
</background>
<description>
<p>
Multiple vulnerabilities have been found in ClamAV:
</p>
<ul>
<li>The
vendor reported a Divide-by-zero error in the PE ("Portable
Executable"; Windows .exe) file handling of ClamAV
(CVE-2008-6680).</li>
<li>Jeffrey Thomas Peckham found a flaw in
libclamav/untar.c, possibly resulting in an infinite loop when
processing TAR archives in clamd and clamscan (CVE-2009-1270).</li>
<li>Martin Olsen reported a vulnerability in the CLI_ISCONTAINED macro
in libclamav/others.h, when processing UPack archives
(CVE-2009-1371).</li>
<li>Nigel disclosed a stack-based buffer overflow
in the "cli_url_canon()" function in libclamav/phishcheck.c when
processing URLs (CVE-2009-1372).</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user or automated system to process a
specially crafted UPack archive or a file containing a specially
crafted URL, possibly resulting in the remote execution of arbitrary
code with the privileges of the user running the application, or a
Denial of Service. Furthermore, a remote attacker could cause a Denial
of Service by supplying a specially crafted TAR archive or PE
executable to a Clam AntiVirus instance.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Clam AntiVirus users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-antivirus/clamav-0.95.2&quot;</code>
</resolution>
