<title>ClamAV: Multiple vulnerabilities</title>
<synopsis>
Multiple vulnerabilities in ClamAV may result in the remote execution of
arbitrary code.

<p>
Clam AntiVirus is a free anti-virus toolkit for UNIX, designed
especially for e-mail scanning on mail gateways.
</p>
</background>
<description>
<p>
Multiple vulnerabilities have been reported:
</p>
<ul>
<li>
Damian Put reported a heap-based buffer overflow when processing PeSpin
packed PE binaries (CVE-2008-0314).
</li>
<li>
Alin Rad Pop of Secunia Research reported a buffer overflow in the
cli_scanpe() function when processing Upack PE binaries
(CVE-2008-1100).
</li>
<li>
Hanno Boeck reported an infinite loop when processing ARJ archives
(CVE-2008-1387).
</li>
<li>
Damian Put and Thomas Pollet reported a heap-based buffer overflow when
processing WWPack compressed PE binaries (CVE-2008-1833).
</li>
<li>
A buffer over-read was discovered in the rfc2231() function when
producing a string that is not NULL terminated (CVE-2008-1836).
</li>
<li>
An unspecified vulnerability leading to "memory problems" when scanning
RAR files was reported (CVE-2008-1837).
</li>
<li>
Thierry Zoller reported that scanning of RAR files could be
circumvented (CVE-2008-1835).
</li>
</ul>
</description>
<impact type="high">
<p>
A remote attacker could entice a user or automated system to scan a
specially crafted file, possibly leading to the execution of arbitrary
code with the privileges of the user running ClamAV (either a system
user or the "clamav" user if clamd is compromised), or a Denial of
Service.
</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 ">=app-antivirus/clamav-0.93"</code>
</resolution>
