Sigreturn-oriented programming
Sigreturn-oriented programming (SROP) is a computer security exploit technique that allows an attacker to execute code in presence of security measures such as non-executable memory and code signing. It was presented for the first time at the 35th IEEE Symposium on Security and Privacy in 2014 where it won the best student paper award.
