Pwntools Pull Request
Thanks for contributing to Pwntools! Take a moment to look at
CONTRIBUTING.mdto make sure you're familiar with Pwntools development.Please provide a high-level explanation of what this pull request is for.
Adding a utility class for glibc's __exit_funcs. This can be helpful when promoting an arbitrary write and read to RCE.
See this resource for more info. A lot of exploits just use the CxaFunc and ExitHandler class shown here, so it would make sense to have the functionality in pwntools as well.
TODO
