Security researcher Mariusz Mlynski reported, through HP Zero Day Initiative's Pwn2Own contest, a method to run arbitrary scripts in a privileged context. This bypassed the same-origin policy protections by using a flaw in the processing of SVG format content navigation.
An incomplete version of this fix was shipped in Firefox 36.0.3 and Firefox ESR 31.5.2.
