Register spring

In computer security, a register spring is a sort of trampoline. It is a bogus return pointer or Structured Exception Handling (SEH) pointer which an exploit places on the call stack, directing control flow to existing code (within a dynamic-link library (DLL) or the static program binary). This target code in turn consists of a call or jump such as "CALL EBX" or "JMP ESP", where the appropriate processor register was previously prepared by the exploit to point to where the payload code begins.
