The flaw deals with escalated privileges of a user process that has access to the X server. The founder of ITL said of the flaw, 'The attack allows a (unpriviliged) user process that has access to the X server (so, any GUI application) to unconditionally escalate to root (but again, it doesn't take advantage of any bug in the X server!). In other words: any GUI application (think e.g. sandboxed PDF viewer), if compromised (e.g. via malicious PDF document) can bypass all the Linux fancy security mechanisms, and escalate to root, and compromise the whole system.' This has apparently been a security flaw since kernel 2.6 was released. From the article, 'On 13 August, Linus Torvalds committed an initial fix, but several patches were added afterward for various reasons. The problem has been addressed in versions 184.108.40.206, 220.127.116.11, 18.104.22.168 and 22.214.171.124 of the kernel.'

A small(ish) device worn around the neck is used to track the hand position, allowing the user to draw, type or gesture in the air. You think it looks ridiculous when you can't tell that folks are talking on a cell phone? Imagine a bus full of people gesturing in thin air. Also, don't forget to turn this thing off, or it will look like your cat was walking on your keyboard.
Free video website Hulu plans to soon begin charging customers and is looking to expand its content to consumer devices like the Xbox and iPad, according to two sources, as the site's media owners experiment with platforms beyond an ad-supported TV model.
Those sources and another with knowledge of the matter said that Hulu, the website for TV viewing owned by News Corp, General Electric's NBC Universal and Walt Disney Co, was developing a subscription service to be rolled out on multiple devices in the next month or two. It was not clear if that service would be offered before Hulu is available on devices.
One of those devices is expected to be Microsoft Corp's Xbox, which also features Netflix Inc's movie streaming service, one of the sources said on Tuesday. Another one of the sources said Hulu was also working to offer its service on Apple Inc's iPad.
