+Advanced exploitation techniques based on code reuse, do not introduce new code in vulnerable
+programs. Code reuse attacks are based on diverting the control flow of an application by overwriting
+function pointers and return addresses. The Shadow Stack and Landing Pads task group will define
+privileged and unprivileged ISA extensions that can be used by privileged and unprivileged programs
+to protect the integrity of their control-flow. Specifically, for protecting backward-edges we will define
+a shadow stack for storing return-addresses in each privilege level. For protecting forward-edges we will
+design a flexible label based landing pads approach which will ensure that the execution adheres to the
+application’s Control-Flow Graph. The design will follow the threat model compiled in CFI-SIG and will be
+updated on demand.
