CWE-432 Dangerous Signal Handler not Disabled During Sensitive Operations

The product uses a signal handler that shares state with other signal handlers, but it does not properly mask or prevent those signal handlers from being invoked while the original signal handler is still running.

• Integrity: Modify Application Data — If two handlers share state - such as global variables - then an attacker can corrupt the state by sending another signal before the first handler has completed execution.

• [Implementation] Turn off dangerous handlers when performing sensitive operations.
