Hole In Linux Kernel Provides Root Rights 274

Posted by Soulskill
from the everything-old-is-new-again dept.
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.

Software patents are clearly a huge mistake. The US should never have allowed them. They are costing business in the US a fortune and do nothing to protect the little guy inventor with the next idea that will change the world. They are simply a tax on innovation and must be stopped immediately.

The White House Listed On Real Estate Website 123

Posted by samzenpus
from the been-for-sale-for-years dept.
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

from the maybe-it-just-takes-more-than-6-weeks dept.
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."

+ - 'Killing in the Name' UK No. 1 thanks to Facebook-> 2

Josh04 (1596071) writes "Due to a 900,000+ Facebook campaign, 90's rap metal group Rage Against the Machine are this year's Christmas number 1, beating out Simon Cowell's X-Factor contestant Joe McElderry to the top spot, making 'Killing in the Name' the first ever UK download-only Christmas number 1. The popular 90's rock song had support from celebrities and the BBC, who got in trouble earlier in the week for allowing five 'fucks' to slip through the censor on a live performance."

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.

+ - Bug power makes salt water sweet ->

Submitted by ewenc
ewenc (1385899) writes "It's not often that bacteria make water more drinkable, but a new microbial desalination cell does precisely that, according to a story in New Scientist. The proof-of-principle system removed 90 per cent of the salt from a seawater-like solution.Microbial desalination could offer big advantages over the methods currently used to purify seawater, which require enormous pressure to operate, and gobble up huge amounts of energy. The experimental microbial desalination cell could eventually run on waste water, scientists say. Full disclosure: I work for New Scientist."
