Security firms warned users of Apple's Mac OS X earlier this week about the existence of an exploit that could result in the execution of arbitrary code. The news has made upgrading to version 10.4.7 even more important, as the update fixes the issue. The vulnerability lies in an operating system file called "launchd."The proof-of-concept code was created by Digital Munition security researcher Kevin Finisterre. He has written other exploits in the past, including another for a Bluetooth flaw within Mac OS X. Finisterre says he does his work out of a desire to show those who believe the operating system is completely safe that there are flaws that need to be addressed.

Lets have a sneak peek into the future of desktop computing. Imagine ur browser window being turned up into a desktop of it own, with sub-windows for other stuffs like chatting, browsing, office programs etc...But these things will not be bothering ur hardware resources much(infact not even little). Well such kind of online OS will be machine independent too. All u need is a gadget to connect to net, a screen and a keyboard.Just because net is in fashion these days and that this idea is sounding very great and innovative, doesnt mean that this can replace the Windows. Even small kids can write software for any purpose these days. But imagine such kind of product being carried on a billion-dollar budget at a place nobody is certain about. Yes i m talking about the very much speculated mythical Google PC that's allegedly being secretly developed in Silicon Valley—or in China or on a Ukrainian IRC channel.It makes sense for Google to develop a Web-based PC. To be clear, a Google PC needn't involve a new gadget like the "thin client" gear of the 1990s. Every computer in the world is capable of running a Web browser. We might not realize it, but we all already have Google PCs.You could still run Windows on a Google PC; it just wouldn't matter if you did or not. Most Google PC rumors imagine a low-priced, Windows-less, entry-level computer for the Wal-Mart set. That could be part of the plan, but it would just be one more option. Instead of trying to convince every consumer on the planet to buy a new machine, it makes a lot more sense for Google to build a super-service that you could log into from any computer, phone, or television, or car and airplane seatback. You would be able to access your files anywhere by logging in, calling up your desktop, and popping into Google's array of Gmail-like applications for word processing, photo editing, and anything else you can think of.If we try to analyze the advantages of an online OS then we might end up with the following conclusions:It could offer more file space, faster searches, guaranteed backups, cheaper software costs, login-from-anywhere portability, and far less home maintenance. Let's skip ahead, though, to the most counterintuitive advantage: Dollar for dollar, network-based computers are faster.And the most important backdrop is the requirement of a highly efficient network for the people who want to use such a thing.If this happens for real... then who wudnt mind saving $2000 from being spent on a Windows Vista.
