Package        : html2ps
Vulnerability  : arbitrary code execution
Problem-Type   : local
Debian-specific: no

The SuSE Security Team found a vulnerability in html2ps, a HTML to
PostScript converter, that opened files based on unsanitized input
insecurely.  This problem can be exploited when html2ps is installed
as filter within lrpng and the attacker has previously gained access
to the lp account.

These problems have been fixed in version 1.0b3-1.1 for the current
stable distribution (woody), in version 1.0b1-8.1 for the old stable
distribution (potato) and in version 1.0b3-2 for the unstable
distribution (sid).

We recommend that you upgrade your html2ps 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.
