New! Plugin Severity Now Using CVSS v3

The DNS server running on the remote host is affected by a denial of service vulnerability.


According to its self-reported version number, the MaraDNS server running on the remote host is affected by a memory leak issue when a DNS packet with a value other than zero is in the Opcode field or a value other than one is in the Class field. This issue could allow a remote attacker to cause a remote denial of service via memory exhaustion by sending large amounts of specially crafted DNS packets.


Upgrade to MaraDNS version / 1.3.05 or later or apply the relevant patch.
