The remote name server, according to its version number, is affected by the following vulnerabilities :
When running the recursive DNS functionality, this server is vulnerable to a buffer overflow attack that may let an attacker execute arbitrary code on the remote host.
It is vulnerable to a denial of service attack (crash) via SIG RR elements with invalid expiry times.
It is vulnerable to a denial of service attack when a DNS lookup is requested on a nonexistent sub-domain of a valid domain and an OPT resource record with a large UDP payload is attached, the server may fail.
