Description Doran Moppert 2017-08-08 02:53:37 EDT
A use-after-free vulnerability when manipulating the DOM during the resize event of an image element. If these elements have been freed due to a lack of strong references, a potentially exploitable crash may occur when the freed elements are accessed.
