If a group item contains a pointer, and the ILE COBOL compiler cannot determine the offset relative to a 16-byte boundary, the ILE COBOL compiler issues a warning message, and the pointer move is attempted.

Webenhanced scheme for pointer signing that enforces pointer integrity for all code and data pointers. We also propose run-time type safety which constrains pointer substitution attacks by ensuring the pointer is of the correct type. Pointer signing and run-time type safety are effective against both control-flow and data-oriented attacks.

WebCode-Pointer Integrity ( CPI) is a property of C/C++ programs that guarantees absence of control-flow hijack attacks by requiring integrity of all direct and indirect pointers to code. Code-Pointer Separation ( CPS) is a simplified version of CPI that provides strong protection against such attacks in practice. WebMay 31, 2024 · Code Pointer Integrity (CPI) [ 22] is a recent addition to the family of defenses to provide integrity of code pointers in a program and thereby prevent control-flow hijacking attacks. The core of CPI is a C-based language front-end of LLVM called SafeStack that splits the regular stack into two parts: a safe stack and an unsafe stack.

WebMemory-corruption attacks such as code-reuse attacks and data-only attacks have been a key threat to systems security. To counter these threats, researchers have proposed a variety of defenses, including control-flow integrity (CFI), code-pointer integrity (CPI), and code (re-)randomization.

Another instruction removes and authenticates the signature after reading the pointer back from memory.

WebIn particular, control-flow integrity (CFI), code-pointer integrity (CPI), and fine-grained code randomization are effective mitigation techniques against code-reuse attacks. All of these techniques require strong memory isolation.
