Synopsis

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

Description

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 127.0.0.1 and make the remote DNS server enter into an infinite loop, therefore denying service to legitimate users.

Solution

Contact the vendor for an appropriate upgrade.
