<br></dd>
<br><dt>More information:</dt>
<dd>Multiple security holes were found in clamav: <br>
<br>
CVE-2005-2070 <br>
<br>
The ClamAV Mail fILTER (clamav-milter), when used in Sendmail using long <br>
timeouts, allows remote attackers to cause a denial of service by keeping <br>
an open connection, which prevents ClamAV from reloading. <br>
<br>
CVE-2005-1923 <br>
<br>
The ENSURE_BITS macro in mszipd.c for Clam AntiVirus (ClamAV) allows remote <br>
attackers to cause a denial of service (CPU consumption by infinite loop) <br>
via a cabinet (CAB) file with the cffile_FolderOffset field set to 0xff, <br>
which causes a zero-length read. <br>
<br>
CVE-2005-2056 <br>
<br>
The Quantum archive decompressor in Clam AntiVirus (ClamAV) allows remote <br>
attackers to cause a denial of service (application crash) via a crafted <br>
Quantum archive. <br>
<br>
CVE-2005-1922 <br>
<br>
The MS-Expand file handling in Clam AntiVirus (ClamAV) allows remote <br>
attackers to cause a denial of service (file descriptor and memory <br>
consumption) via a crafted file that causes repeated errors in the <br>
cli_msexpand function. <br>
<br>
CVE-2005-2450 <br>
<br>
Multiple integer overflows in the (1) TNEF, (2) CHM, or (3) FSG file <br>
format processors in libclamav for Clam AntiVirus (ClamAV) allow remote <br>
attackers to gain privileges via a crafted e-mail message. <br>
</dd>
<br><dt>For the testing distribution (etch) this is fixed in version 0.86.2-4etch1</dt>
<dt>For the unstable distribution (sid) this is fixed in version 0.86.2-1</dt>
<br><dt>This upgrade is recommended if you use clamav.<dt>
<br><dt>If you have the secure testing lines in your sources.list, you can update by running this command as root:</dt>
<dd>apt-get update && apt-get upgrade</dd>
<br>
<dt>The Debian testing security team does not track security issues for then stable (sarge) and oldstable (woody) distributions. If stable is vulnerable, the Debian security team will make an announcement once a fix is ready.</dt>
<br>
<dt>To use the Debian testing security archive, add the following lines to your /etc/apt/sources.list:<dt>
<br>
<dd>deb http://secure-testing.debian.net/debian-secure-testing etch/security-updates main contrib non-free</dd>
<dd>deb-src http://secure-testing.debian.net/debian-secure-testing etch/security-updates main contrib non-free</dd>
<br>
<dt>The archive signing key can be downloaded from<dt>
