Package : tar
Vulnerability : input validation error
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2006-6097
BugTraq ID : 21235
Debian Bug : 399845

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.
