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 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.
