Package        : clamav
Vulnerability  : buffer overflow, stack consumption
Problem type   : local (remote)
Debian-specific: no
CVE Id(s)      : CVE-2008-5050 CVE-2008-5314
Debian Bug     : 505134 507624

Moritz Jodeit discovered that ClamAV, an anti-virus solution, suffers
from an off-by-one-error in its VBA project file processing, leading to
a heap-based buffer overflow and potentially arbitrary code execution
(CVE-2008-5050).

Ilja van Sprundel discovered that ClamAV contains a denial of service
condition in its JPEG file processing because it does not limit the
recursion depth when processing JPEG thumbnails (CVE-2008-5314).

For the stable distribution (etch), these problems have been fixed in
version 0.90.1dfsg-4etch16.

For the unstable distribution (sid), these problems have been fixed in
version 0.94.dfsg.2-1.

The testing distribution (lenny) will be fixed soon.

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.
