Description
Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that there was a remaining dangling pointer issue leftover from the fix to CVE-2010-2753. Under certain circumstances one of the pointers held by a XUL tree selection could be freed and then later reused, potentially resulting in the execution of attacker-controlled memory.
