Debian DSA 176-1 Critical: gv Remote Code Execution Risk

Zen-parse discovered a buffer overflow in gv, a PostScript and PDF
viewer for X11. This problem is triggered by scanning the PostScript
file and can be exploited by an attacker sending a malformed
PostScript or PDF file. The attacker is able to cause arbitrary code
to be run with the privileges of the victim.

This problem has been fixed in version 3.5.8-26.1 for the current
stable distribution (woody), in version 3.5.8-17.1 for the old stable
distribution (potato) and version 3.5.8-27 for the unstable
distribution (sid).

We recommend that you upgrade your gv package.

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.
