Name of the Vulnerable Software and Affected Versions Cisco Prime Network Registrar versions prior to 8.3.5

Description A vulnerability in the DNS input packet processor could allow an unauthenticated, remote attacker to cause the DNS process to momentarily restart, leading to a partial denial of service (DoS) condition. The issue is due to incomplete DNS packet header validation when a packet is received. An attacker could exploit this by sending a malformed DNS packet, allowing them to cause the DNS process to restart and potentially lead to a DoS condition.
