Package        : clamav
Vulnerability  : heap overflow
Problem type   : remote
Debian-specific: no
CVE IDs        : CVE-2006-0162
Debian Bug     : 320014

A heap overflow has been discovered in ClamAV, a virus scanner, which
could allow an attacker to execute arbitrary code by sending a carefully
crafted UPX-encoded executable to a system runnig ClamAV. In addition,
other potential overflows have been corrected.

Packages for the ARM architecture were not available when DSA 947-1 was
released; these packages are now available. Also, DSA 947-1 incorrectly
identified the package version which corrected these issues in the
unstable distribution (sid).

The old stable distribution (woody) does not include ClamAV.

For the stable distribution (sarge) this problem has been fixed in
version 0.84-2.sarge.7.

For the unstable distribution (sid) this problem has been fixed in
version 0.88-1.

We recommend that you upgrade your clamav package immediately.


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.


Debian GNU/Linux 3.1 alias sarge
