# Script audit and contributions from Carmichael Security 
#      Ian Koenig <[email protected]> (nb: this domain no longer exists)
#      Added BugtraqID and CVE
#      Updated to handle two specific types of attacks instead of just a general
#        statement of "vulnerable to DNS storm attacks".

"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.");
