Apple fixes critical QuickTime bug

Apple has patched a critical QuickTime security flaw in its QuickTime 7.4.1 update.

Apple has released a security fix for its QuickTime media player software, fixing a critical bug that had been worrying security experts for nearly a month.

The update, released Wednesday, fixes a vulnerability in the Real Time Streaming Protocol (RTSP) used by QuickTime to handle streaming media.

On January 10, researcher Luigi Auriemma disclosed the flaw by posting proof-of-concept attack code that could be used to run unauthorized software on a victim's computer. For the attack to work, the criminal would have to first trick the user into viewing a maliciously encoded QuickTime media file.

With the attack code available, security researchers had been hoping that Apple would address the flaw. Wednesday's QuickTime 7.4.1 update is for both the Mac OS X and Windows operating systems.

It is Apple's fifth QuickTime update since October. The company has been forced to issue the flurry of patches as security researchers have taken a closer look at media player flaws during the past year. In December, Apple patched a separate RTSP vulnerability, which online criminals had already started to use in their attacks.

"In the past few months, QuickTime has been a prevalent target for security researchers," said Andrew Storms, director of security operations with nCircle Network Security, via instant message. "Internet media applications on the desktop have been a rich target for attackers and this trend is sure to continue as most users aren't yet accustomed to attacks arriving in the form of a viral video."

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
