  - A PAN-OS URL filtering policy misconfiguration could allow a network-based attacker to conduct reflected
    and amplified TCP denial-of-service (RDoS) attacks. The DoS attack would appear to originate from a Palo
    Alto Networks PA-Series (hardware), VM-Series (virtual) and CN-Series (container) firewall against an
    attacker-specified target. (CVE-2022-0028)
