This protocol anomaly triggers when it detects a DNS request/reply with a pointer that points beyond the data end. This can indicate a buffer overflow or denial-of-service (DoS) attempt.
Detection of malformed DNS datagrams may indicate a software configuration error. It could also indicate that a malicious attempt to create a buffer-overflow condition is underway.
