Hole In Linux Kernel Provides Root Rights 274

oztiks writes with this excerpt from The H: "A vulnerability in the 32-bit compatibility mode of the current Linux kernel (and previous versions) for 64-bit systems can be exploited to escalate privileges. For instance, attackers can break into a system and exploit a hole in the web server to get complete root (also known as superuser) rights or permissions for a victim's system. According to a report, the problem occurs because the 32-bit call emulation layer does not check whether the call is truly in the Syscall table. Ben Hawkes, who discovered the problem, says the vulnerability can be exploited to execute arbitrary code with kernel rights. ... Hawkes says the vulnerability was discovered and remedied back in 2007, but at some point in 2008 kernel developers apparently removed the patch, reintroducing the vulnerability. The older exploit apparently only needed slight modifications to work with the new hole."

Nice answer but you've forgetting that an "idea" has nothing to do with research, has nothing to do with how well you can mass produce it or any of the other distractions to my argument. You can't plan an idea, you can only influence peoples minds with facts, experience etc in the hope that something original will come out of it. Whether you came up with the idea or not, building a factory and/or pumping out products has nothing to do with the act of inventing. Inventors (which I include myself as) come up with good ideas because they have a deep interest in the subject. I have spent no money coming up with great ideas. It is a fallacy that the idea costs time/money.... it's the education/knowledge/experience necessary to come up with great ideas that does. Software should be considered in the same spirit as business processes, art, music and mathematics.

The problem as I see it is that the inventor of an idea may not have created the best implementation of that idea. Someone else may come along and want to create a better product that uses the (unchanged) original patent, but they can't because the inventor sees this as competition. Who should suffer? The individual inventor, or society at large by putting up with an inadequate product? Software patents are a monopoly on ideas in an industry where ideas are the building blocks of progress.

The White House Listed On Real Estate Website 123

Forget visiting the White House, if you have $10 million you can own it. At least that is the price for the president's home on the real estate website Redfin. From the article: "Obviously this is an error. It looks like Redfin software pulled an example listing from the website Owners.com by mistake. That example listing was the White House. We have e-mailed Redfin for comment." I know it's historic but it still looks a bit on the high side according to the comparables in the area.

Brain Training Games Don't Train Your Brain 151

Stoobalou writes with this excerpt from Thinq.co.uk: "A new study has shown that brain training games do little to exercise the grey matter. Millions of people who have been prodding away at their Nintendo DS portable consoles, smug in the knowledge that they are giving their brains a proper work-out, might have to rethink how they are going to stop the contents of their skulls turning into mush."

I agree, this is a demographically skewed answer by the looks of things. I'm sure if Slashdot geoIP'd their users they would find that most of them in North America and Europe. In Brazil they make pizza with more toppings and less base (whereas in the UK, where I'm from, it's more base and less topping). Some pizzas I've had in Brazil have about an inch of topping.

You are so right. I'm a Brit living in Sao Paulo Brazil, and my I can tell you that South America can be a very dangerous place. Being western tourist with a laptop and NOT being robbed/kidnapped after flashing it around at every wifi hotspot means that you've been a lucky SOB. Only last week a coffee shop near here was held up at gunpoint and all the customers robbed of all their laptops.

Submission + - Why the Google Phone Isn't Taking Off 2

Hugh Pickens writes: "Farhad Manjoo writes in Slate that while the iPhone commands nearly 14 percent of smartphone sales and BlackBerry about 21 percent. Android has only 3 percent and that even though it's far friendlier to developers, Android has failed to attract anywhere near the number of apps now clogging the iPhone. Manjoo writes that Google went wrong by giving handset manufacturers and carriers a great deal of control over the design and marketing of Android phones so there is no idealized "Google phone"--instead, Android devices get names like the T-Mobile G1 or the myTouch 3G, and each is marketed separately and comes with its own distinct capabilities and shortcomings. "Outside handset manufacturers lack ambition--none of them even seems to be trying to match the capabilities of the iPhone, let alone to knock us down with features that far surpass those of Apple's device," writes Manjoo. "A smart handset manufacturer could build a top-of-the-line Android device that outshines Apple's phone in at least a few areas--better battery life, a much better Web browser, a brighter or bigger screen, faster or more functional controls ... something that might help Android inspire gadget lust. But so far, that's not happening." John Gruber adds that the goal should be to make a phone that is better than the iPhone. "Carefully select a handful of areas where you can beat the iPhone, and then promote the hell out of these features," writes Gruber. "If your hope is to gain a strong foothold in the market with a sub-par device, you are mistaken. If Apple is BMW, you can be Porsche.""

WebGL Standard To Bring 3D Acceleration To Browsers? 239

Several sources are reporting that while native audio/video support has been dropped from the HTML 5 spec, the Khronos Group has released a few details about their up and coming WebGL 3D acceleration standard. "The general principle behind WebGL is to offer a JavaScript binding to the group's OpenGL ES 2.0 system, allowing code run within the browser to access the graphics hardware directly in the same way as a standalone application can. As the technology would rely solely on JavaScript to do the heavy lifting, no browser plugin would be required — and it would be compatible with any browser which supports the scripting language alongside the HTML 5 'Canvas' element."

30,000-Lb. Bomb On Fast Track For Deployment 707

coondoggie writes "Published reports today say the Pentagon is rattling swords in the direction of North Korea and Iran by speeding the development a 20-foot, 30,000-lb bomb known as Massive Ordnance Penetrator. This weapon is intended to annihilate underground bunkers and other hardened sites (read: long-range missile or underground nuke development) up to 200 ft. underground. The Defense Threat Reduction Agency, which has overseen the development of this monster since 2007, says it is designed to be carried aboard B-2 and B-52 bombers and deployed at high altitudes, from which it would strike the ground at speeds well beyond twice the speed of sound to penetrate the below-ground target." Reuters has more specifics on the MOP's chances for deployment by 2010, and the detail that the bomb's load of explosives weighs in at 5,300 lbs.
