COVERT DISCOVERS VULNERABILITIES IN DNS SERVER SOFTWARE.

The COVERT Labs (Computer Vulnerability Emergency Response Team) at PGP Security, a Network Associates business (NASDAQ: NETA), Santa Clara, Calif., has discovere high-risk vulnerabilities in the BIND 4 and BIND 8 DNS server software from the Internet Software Consortium (ISC). These vulnerabilities could allow a remote attacker to launch a denial of service attack, hijack domain names, or compromise a vulnerable DNS server.

BIND is a core part of the Internet's domain name resolution infrastructure - allowing the conversion of domain names into numeric Internet Protocol (IP) addresses. These numeric IP addresses are required for any information to reach its intended destination on the Internet. Exploitation of these vulnerabilities could potentially disrupt all Internet-based communication that relies on a domain name, effecting every company that maintains a Web site or that utilizes e- mail as a communication tool.

"If this vulnerability was exploited by an attacker, all Internet traffic relying on a vulnerable server could be brought to a halt," said Jim Magdych, manager of the COVERT Labs at PGP Security. "Additionally, depending on a corporation's network configuration, a hacker could take advantage of the vulnerability to compromise the server and launch further attacks - potentially allowing the attacker access to their internal network."

COVERT Labs discovered the vulnerability while conducting research into core services of the Internet infrastructure and immediately contacted ISC to help develop a patch for all affected users.
