Developing a remote exploit is not easy. It requires a comprehensive understanding of a vulnerability and delicate techniques to bypass defense mechanisms.  ...  One such adaptation is the replacement of the original shellcode (i.e., the attacker-injected code that is executed as the final step of the exploit) in the original exploit with a replacement shellcode  ...  We would also like to thank Alexandre Rebert, Matthew Maurer and Vyas Sekar for their comments on the project.  ...
