A new exploit which attacks seven unpatched holes in the Mac OS X platform, could shake the Apple platforms reputation for security.

Independent security researcher Tom Ferris posted "proof of concept" code on Friday that can use newly discovered and unpatched bugs in the OS X operating system and Safari browser, to crash applications or even run unauthorised code on the Mac.

"There [seem] to be some problems with the claimed solid-as-a-rock Unix OS," he wrote on his blog. "Getting Safari to crash in many different spots is trivial, where Firefox is very tough."

Apple Computer has already been made aware of the bugs and plans to fix them in "the next security release," Ferris said in his Security-protocols.com blog.

Long considered to be more secure than Microsoft's Windows operating system, Mac OS X has increasingly been the focus of security researchers like Ferris. In February a number of malicious programs, including one called OSX/Leap, were released targeting the Macintosh.

The SANS Institute's Internet Storm Center rated Ferris's bugs as "highly critical," and warned that there are no patches or workarounds available for the majority of these vulnerabilities.

Ferris made headlines earlier this year when he discovered a bug in the Internet Explorer 7 Beta 2 preview browser within minutes of the product being released.

Apple representatives were not immediately available to comment for this story.
