Cache Corruption on Microsoft DNS Servers
Release Date: August 31, 2001
Systems Affected
Microsoft Windows NT 4.0 and Windows 2000 systems running Microsoft DNS Server
The CERT/CC has received reports from sites experiencing cache corruption on systems running Microsoft DNS Server. The default configuration of this software allows data from malicious or incorrectly configured servers to be cached in the DNS server. This corruption can result in erronous DNS information later being returned to any clients which use this server.
