Debian: New UUCP packages fix local exploit

zen-parse has found a problem with Taylor UUCP as distributed with many GNU/Linux distributions. It was possible to make `uux' execute 'uucp' with malicious commandline arguments which gives an attacker access to files owned by uid/gid uucp. Fixed packages are available from security.debian.org.

Package        : uucp
Vulnerability  : uucp uid/gid access
Problem-Type   : local exploit
Debian-specific: no

zen-parse has found a problem with Taylor UUCP as distributed with
many GNU/Linux distributions.  It was possible to make `uux' execute
`uucp' with malicious commandline arguments which gives an attacker
access to files owned by uid/gid uucp.

This problem has been fixed in version of 1.06.1-11potato1 for Debian
GNU/Linux 2.2 by using a patch that RedHat has provided.

We recommend that you upgrade your uucp package immediately.

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.
