Apple update finally fixes important DNS bug
Apple has released a security update for its Mac OS X operating system, fixing a critical Internet security flaw that the company had failed to properly patch in late July.
The Mac OS X v. 10.5.5 security update was released Monday, fixing security bugs in Apple's software as well as several open-source components that ship with the operating system. In all, more than 25 bugs have been patched.
But the Internet flaw, which has to do with the Domain Name System (DNS), is the most widely publicized issue. Apple, like many other operating-system vendors, was forced to patch its DNS software after security researcher Dan Kaminsky discovered a fundamental bug in the way this type of software is built.
