CWmike writes "A security researcher is criticizing Apple for lagging with its response to the DigiNotar certificate fiasco. He is urging the company to quickly update Mac OS X to protect users. 'We're looking at some very serious issues [about trust on the Web] and it doesn't help matters when Apple is dragging its feet,' said Paul Henry, a security and forensics analyst with Lumension. Unlike Microsoft, which updated Windows on Tuesday to block all SSL certificates issued by DigiNotar, Apple has not updated Mac OS X to do the same. Meanwhile, even Mac OS X users who want to go DIY are stymied, reports Bob McMillan, because the OS can't properly revoke dodgy digital certificates."
