AsyncFreeSnowWhite - a Disney story.

In Spidermonkey is there a way of immediately creating an object on the Tenured heap without having to send it their via gc ?

Before its public release my attempt at reversing CVE-2023-2033 was a failure. I got close in that i identified there was some difference in behavior between AccessorInfo and AccessorPair but I got lost. I didn't realize that you had to exploit re-entrancy

CVE-2024-0519 is the vuln that got away. The swiftness of the patch has resisted attempts at reversing it so far. We know you can create a object where unused property fields = 0 but in reality it is bigger. This is known in the comments. However doesnt seem useful. What is the initial primitive ?

Re: The ITW CVE-2024-9680 exploit. I don't understand the purpose of the XSLT stuff. Doesn't really seem necessary ? Or We're they using it as an alloc primitive ?

Re: CVE-2024-9680 - the use of setTimeout to call "getInfo" is an odd choice. Wouldn't just using the promise resolution itself be better ?

As we suspected the ITW exploit for CVE-2024-9680 was definitely inspired by CVE-2022-0609. Just look at the variable names and other choices - such as creating a Animation object via "animate" function instead of constructor, he check for "if (this.toString() == "[object Animation]")" too.
