[DSA 192-2] New html2ps packages correct fix against arbitrary code execution

by Nikola Strahija on December 6th, 2002 The security update from DSA 192-1 contained a syntax error which is now fixed. For completeness we include the text of the old advisory:


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.

This problem has been fixed in version 1.0b3-1.2 for the current
stable distribution (woody), in version 1.0b1-8.2 for the old stable
distribution (potato) and in version 1.0b3-3 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.
