Zusammenfassung:An apparatus and method for enforcing control-flow integrity (CFI) may include obtaining assembly code; patching the assembly code to produce patched code including control-flow integrity (CFI) enforcement; and assembling the patched code into a binary output. Patching may include adding, to assembly code of a function, at least one of: assembly code for storing and validating a stack-cookie and assembly code for validating a return address.
