Remember how we kept on hearing about how much more secure MacOS was than Linux? Here is a pitfall of not having many eyes. . . .
A security hole still threatens Mac OS X users after a patch issued by Apple Computer last week failed to fix the underlying problem, security experts said on Tuesday.

The security issue could allow an attacker to transfer and then run a malicious program on a Mac, if the Mac's user can be enticed to go to a fake Web page on which the program has been placed.

"This, in my mind, is the first critical vulnerability on OS X," said Richard Forno, a security researcher and the former chief of security for domain registrar Network Solutions. "Downloading the patch and seeing that there were some things that were fixed and some things that weren't, tells me that there is more work to be done."
