A flaw in BIND, a widely used software for locating Internet servers, could allow hackers to take companies' Web sites offline. Researchers have discovered a flaw in widely used software for locating Internet servers, which could allow the software to be shut down by hackers or even by accident. Such a shutdown would keep Web browsers, for example, from being able to locate Web sites.

CERT, an Internet security advisory service, on Tuesday warned that the flaw affects Domain Name System (DNS) servers running version 9 of Berkeley Internet Name Domain (BIND) prior to version 9.2.1. Version 9.2.1 is BIND's current release. "Because the normal operation of most services on the Internet depends on the proper operation of DNS servers, other services could be affected if this vulnerability is exploited," wrote CERT's Ian Finlay in a statement.
