BIND 9 Denial of Service Vulnerabilities

Vulnerability Assessment Summary
Checks version of BIND

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote name server may be affected by multiple denial of service
vulnerabilities.

Description :

The version of BIND installed on the remote host suggests that it
suffers from multiple denial of service vulnerabilities, which may be
triggered by either by sending a large volume of recursive queries or
queries for SIG records where there are multiple SIG(covered) RRsets.

Note that Nessus obtained the version by sending a special DNS request
for the text 'version.bind' in the domain 'chaos', the value of which
can be and sometimes is tweaked by DNS administrators.
