Description

Security researcher regenrecht reported a flaw that affected Firefox versions 4 through 8 via TippingPoint's Zero Day Initiative. This flaw is a use-after-free in nsHTMLSelectElement when the parent node of the element is no longer active and could allow for possible remote code execution.

Firefox 3.6 is not affected by this vulnerability.
