StackGuard is a compiler approach for defending programs and systems against “stack smashing” attacks. Stack smashing attacks are the most common form of security vulnerability. Programs that have been compiled with StackGuard are largely immune to stack smashing attacks. Protection requires no source code changes at all. When a vulnerability is exploited, StackGuard detects the attack in progress, raises an intrusion alert, and halts the victim program. Binary release, Terminator canary mechanism.
