Package        : clamav
Vulnerability  : integer overflows, infinete loop
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2005-2450
BugTraq ID     : 14359

Several bugs were discovered in Clam AntiVirus, the antivirus scanner
for Unix, designed for integration with mail servers to perform
attachment scanning.  The following problems were identified:


    Neel Mehta and Alex Wheeler discovered that Clam AntiVirus is
    vulnerable to integer overflows when handling the TNEF, CHM and
    FSG file formats.


    Mark Pizzolato fixed a possible infinete loop that could cause a
    denial of service.

The old stable distribution (woody) is not affected as it doesn't contain clamav.

For the stable distribution (sarge) these problems have been fixed in
version 0.84-2.sarge.2.

For the unstable distribution (sid) these problems have been fixed in
version 0.86.2-1.

We recommend that you upgrade your clamav package.

sources.list as given below:

apt-get update
        will update the internal database
