Package        : apt-cacher
Vulnerability  : missing input sanitising
Problem-Type   : remote
Debian-specific: yes
CVE ID         : CAN-2005-1854

Eduard Bloch discovered a bug in apt-cacher, a caching system for
Debian package and source files, that could allow remote attackers to
execute arbitrary commands on the caching host as user www-data.

The old stable distribution (woody) does not contain this package.

For the stable distribution (sarge) this problem has been fixed in
version 0.9.4sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 0.9.10.

We recommend that you upgrade your apt-cacher package.


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.
