C++ (Cpp) smash_stack_dummy_function Examples

Example #1

File: crasher.cpp Project: ArtBears/platform_system_core

// This must be marked with "__attribute__ ((noinline))", to ensure the
// compiler generates the proper stack guards around this function.
// Assign local array address to global variable to force stack guards.
// Use another noinline function to corrupt the stack.
__attribute__ ((noinline)) static int smash_stack(volatile int* plen) {
    printf("crasher: deliberately corrupting stack...\n");

    char buf[128];
    smash_stack_dummy_buf = buf;
    // This should corrupt stack guards and make process abort.
    smash_stack_dummy_function(plen);
    return 0;
}

Example #2

File: crasher.cpp Project: BenzoRoms/system_core

// This must be marked with "__attribute__ ((noinline))", to ensure the
// compiler generates the proper stack guards around this function.
// Assign local array address to global variable to force stack guards.
// Use another noinline function to corrupt the stack.
