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 due to improperly deallocating memory in the IPv6 code. This issue could allow a remote attacker to cause a remote denial of service via memory exhaustion by sending large amounts of invalid DNS packets.


Upgrade to MaraDNS version / 1.3.03 or later or apply the relevant patch.
