Description Josh Bressers 2009-12-11 19:55:24 UTC

Security researcher Gregory Fleischer reported that the exception messages generated by Mozilla's GeckoActiveXObject differ based on whether or not the requested COM object's ProgID is present in the system registry. A malicious site could use this vulnerability to enumerate a list of COM objects installed on a user's system and create a profile to track the user across browsing sessions.
