Windows and Mac users urged to update Safari

Safari
Apple has released version 4.0.5 of its Safari browser, fixing a number of issues with its browser for Windows and Mac OS X including – most importantly – a grand total of 16 security vulnerabilities.

If you dilly-dally over updating your computer, it’s possible that hackers could exploit the security bugs – including some that could mean that simply visiting a webpage with a maliciously crafted image could lead to malicious code being automatically run on your computer.

Interestingly, one of the bugs (CVE-2009-2285) fixed in Safari 4.0.5 was announced and patched in Mac OS X 10.6.2 back in December 2009, and in Mac OS X 10.5 since January, meaning that Windows users of Safari have been vulnerable for over two months to the way their browser handles booby-trapped TIFF images.

But it doesn’t matter whether you own a Mac or PC, if you run Safari the message is clear: It’s time to update your browser and ensure that you are protected against hackers exploiting the security holes detailed in the security advisory on Apple’s website.
