high Nessus Plugin ID 73476

Synopsis

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

Description

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.

Solution

Upgrade to MaraDNS version 1.2.12.06 / 1.3.05 or later or apply the relevant patch.
