I'm compiling vulnerabilities and related attacks, and I need to find a famous attack that exploited a use-after-free vulnerability. I've looked for a while though I can't seem to find any. I know there are lots of times use-after-frees were found in internet explorer and other softwares, though I only get pointed to the vulnerability and update pages, and not specific attacks.
We have found two use-after-free vulnerabilities in PHP’s garbage collection algorithm. Those vulnerabilities were remotely exploitable over PHP’s unserialize function.
