Dangling pointer vulnerability in nsTreeContentView

Description

Security researcher regenrecht reported via TippingPoint's Zero Day Initiative an error in the way <option> elements are inserted into a XUL tree <optgroup>. In certain cases, the number of references to an <option> element is under-counted so that when the element is deleted, a live pointer to its old location is kept around and may later be used. An attacker could potentially use these conditions to run arbitrary code on a victim's computer.

Workaround
