CVE-2009-3987: Infoleak

First published: Fri Dec 11 2009(Updated: )

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.
