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

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.
