You have probably heard by now that there is another Acrobat vulnerability, and that Adobe does not plan to do anything about it until January 12, see http://isc.sans.org/diary.html?storyid=7747
The good news is that we now have a single HKLM registry entry to disable JavaScript for 9.2 and 8.1.7. This article: http://kb2.adobe.com/cps/504/cpsid_50431.html explains the “JavaScript Blacklist Framework”, and the registry files are at http://kb2.adobe.com/cps/532/cpsid_53237.html. This is a welcome change from Adobe.
