Teemu Salmela discovered a vulnerability in GNU tar that could allow a
malicious user to overwrite arbitrary files by inducing the victim to
attempt to extract a specially crafted tar file containing a
GNUTYPE_NAMES record with a symbolic link.

For the stable distribution (sarge), this problem has been fixed in
version 1.14-2.3

For the unstable distribution (sid) and the forthcoming stable release
(etch), this problem will be fixed in version 1.16-2.

We recommend that you upgrade your tar 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.
