Vulnerabilities in the Berkeley Internet Name Domain (BIND) program make it possible for intruders to render Domain Name System (DNS) information unreliable. At the beginning of this year, a version of BIND (4.9.3) became available that fixes several security problems that are being exploited by the intruder community. CERT-NL urges you to install the appropriate patch from your vendor. CERT Coordination Center has released Security Advisory CA-96.02 to tackle this problem. Additional information with regards to this vulnerability is placed in the README file associated with the advisory. You are encouraged to check on README file updates regularly. You can automate that process by using the CERT-NL notifier service. All CERT Coordination Center advisories and README's are mirrored by CERT-NL.
