Mozilla Foundation Security Advisory 2009-40

Title: Multiple cross origin wrapper bypasses Impact: High Announced: July 21, 2009 Reporter: moz_bug_r_a4 Products: Firefox

Fixed in: Firefox 3.5 Firefox 3.0.12 Description

Mozilla security researcher moz_bug_r_a4 reported a series of vulnerabilities in which objects that normally receive a XPCCrossOriginWrapper are constructed without the wrapper. This can lead to cases where JavaScript from one website may unsafely access properties of such an object which had been set by a different website. A malicious website could use this vulnerability to launch a XSS attack and run arbitrary JavaScript within the context of another site. Workaround

Disable JavaScript until a version containing this fix can be installed. References
