Mozilla Foundation Security Advisory 2007-35
Title: XPCNativeWraper pollution using Script object
Impact: Critical
Announced: October 18, 2007
Reporter: moz_bug_r_a4
Products: Firefox, SeaMonkey
Fixed in: Firefox 2.0.0.8
SeaMonkey 1.1.5
Description
Mozilla security researcher moz_bug_r_a4 reported that it was possible to use the Script object to modify XPCNativeWrappers in such a way that subsequent access by the browser chromeâsuch as by right-clicking to open a context menuâcan cause attacker-supplied javascript to run with the same privileges as the user. This is similar to MFSA 2007-25 fixed in Firefox 2.0.0.5
