1. Problem Description
From CERT CA-2002-31:
Multiple vulnerabilities have been found in BIND (Berkeley
Internet Name Domain).
One of these vulnerabilities may allow remote attackers to
execute arbitrary code with the privileges of the user
running named, typically root.
Other vulnerabilities may allow remote attackers to disrupt
the normal operation of your name server, possibly causing a
crash.
A vulnerability in the DNS resolver library may allow remote
attackers to execute arbitrary code with the privileges of
applications that issue network name or address requests.
2. Vulnerable Supported Versions
