Contraindications

Problem description

html2ps contained various insecure open() calls in the perl script which allowed evil constructed HTML input to execute arbitrary commands when converted to postscript.
Since html2ps is used as a printfilter for HTML an update is strongly recommended. As a quick and dirty workaround, the /usr/bin/html2ps file can be removed on printservers. This will make the printing of HTML files impossible and closes the hole until the new package is installed.
