Clam AntiVirus (short: ClamAV) is an anti-virus toolkit for UNIX,
|
||
|
|
designed especially for e-mail scanning on mail gateways.

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>
|
||
|
|

<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.

</workaround>
|

|
|
<resolution>
|
||
|
|
<p>
|
||
|
|
All Clam AntiVirus users should upgrade to the latest version:
|
||
|
|
</p>
|
||
|
|
<code>
|
||
|
|
# emerge --sync
|
||
|
|
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.95.2"</code>
