1.2.7.4. alpha.security.MmapWriteExec (C)
Warn on mmap() calls that are both writable and executable.

Examples:

void test(int n) {
  void *c = mmap(NULL, 32, PROT_READ | PROT_WRITE | PROT_EXEC,
                 MAP_PRIVATE | MAP_ANON, -1, 0);
  // warn: Both PROT_WRITE and PROT_EXEC flags are set. This can lead to
  //       exploitable memory regions, which could be overwritten with malicious
  //       code
}
