Enforcing Forward-Edge Control-Flow Integrity in GCC

Webforward-edge CFI by restricting the permitted function pointer targets and vtables at indirect call sites to a set that the compiler, linker, and runtime have determined to be possibly valid. The third mechanism is a runtime analysis tool designed to catch CFI violations early in the software development life-cycle. Our mechanisms WebAny CFI implemen-tation must limit both forward and backward edges. Research suggests that at least some forward-edge policies can be en-forced efﬁciently in software [15], but backward-edge policies can be more expensive [16]. This has motivated researchers to examine several different backward-edge policies and to WebJul 5, 2024 · To mitigate such threats, Control-Flow Integrity (CFI) is one of the most effective and popular solution, and integrated with the modish hardware makes it even more valuable, for instance, the ARM Pointer Authentication (PA), which can generate a message authentication code for a pointer and verify it to ensure the pointer is intact. other term for biyaya

PICFI ﬁrst pre-computes a static CFG as the upper bound for its dynamic one. PICFI starts with the empty CFG of a program, and during runtime, once a function address is taken (e.g., p= &func), it will add an edge from each indirect callsite to func if this edge is also found in the static CFG. other term for blissful
