Posted By LinuxSecurity Advisories
Ulf H�rnhammar and an anonymous researcher from Germany discovered a vulnerability in the protocol code of freshclam, a command line utility responsible for downloading and installing virus signature updates for ClamAV, the antivirus scanner for Unix. This could lead to a denial of service or potentially the execution of arbitrary code.

Package        : clamav
Vulnerability  : buffer overflow
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2006-1989
BugTraq ID     : 17754

Ulf H�rnhammar and an anonymous researcher from Germany discovered a
vulnerability in the protocol code of freshclam, a command line
utility responsible for downloading and installing virus signature
updates for ClamAV, the antivirus scanner for Unix.  This could lead
to a denial of service or potentially the execution of arbitrary code.

The old stable distribution (woody) does not contain clamav packages.

For the stable distribution (sarge) this problem has been fixed in
version 0.84-2.sarge.9.

For the unstable distribution (sid) this problem has been fixed in
version 0.88.2-1.

We recommend that you upgrade your clamav packages.


Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
