New! Plugin Severity Now Using CVSS v3

The remote DNS server is vulnerable to a denial of service attack.


The remote DNS server is vulnerable to a denial of service attack because it replies to DNS responses.

An attacker could exploit this vulnerability by spoofing a DNS packet so that it appears to come from and make the remote DNS server enter into an infinite loop, therefore denying service to legitimate users.


Contact the vendor for an appropriate upgrade.
