Local Privilege Escalation On All Linux Kernels
QuesarVII writes "Tavis Ormandy and Julien Tinnes have discovered a severe security flaw in all 2.4 and 2.6 kernels since 2001 on all architectures. 'Since it leads to the kernel executing code at NULL, the vulnerability is as trivial as it can get to exploit: an attacker can just put code in the first page that will get executed with kernel privileges.'"
So that's what the NULL pointers were for.

I use Windows!
Or I would be able to, if there were any
Long live the BSD license
Seems to work just fine on your box . . .
Sure there are. And they are both laughing.
everyone go hax the internets! rootkit everything!!!
A sledgehammer is a Denial of Service - Unless you aim it at the head of the operator and threaten to use it.

... I don't get it... Stallman uses Linux...
Well by that logic 99% of windows users haven't used a real windows machine either.
Your post got modded up, too.
Endless arguments over trivial contradictions in books written by ignorant savages to explain thunder in the dark.
Yeah, I know, I nearly cancelled the post after I wrote it.
Desktop Windows /is/ Windows, but Windows Servers are far more inherently secure than Windows Desktops, simply by the way that they're operated. It was a bad comment.
Check out my sysadmin blog!
Aw, cheer up little guy. I thought it was a very nice comment.

And from all across the globe came the sound of geeks crying, for they would soon see their beloved "uptime" reset to zero.
Yeah, that was my fault. Sorry about that. I knew it was there, I just kept putting off fixing it or telling anyone.
Probably don't need to install the patch then. Or keep the machine powered on, for that matter...
You're special forces then? That's great! I just love your olympics!
Well - I'm searching for Linux botnets that have been created by this exploit. Searching . . . searching . . . searching . . .
Dang, I'm not finding any.
How about Windows botnets? WOW, will you just look at all of them? http://www.secureworks.com/research/threats/topbotnets/
I sure wish Linux would get off their dead arses and patch this problem. Sure would be nice if they can get it done in less than a month or six, like Windows!! Oh - wait - what? Linus committed a patch correcting this issue on 13th August 2009.

I guess I'll hold off on pushing the panic button. I see no need to "upgrade" to Windoze, LMAO

This is the windows newbs one chance to stick it to the Unix guys, don't fuck this day up for them!
You must be mistaken. rjstanford is the computer.

Thats what I get for sending you to do the math. Im still too lazy to go check it out and look at methods, years and the rest.
||sarcasm|| I take your analysis as true and hereby declare that windows has been exploited lesser than linux, has less malware against and is inherently less prone to attack than linux or turning into a braindead spamzombie than linux. ||end sarcasm||
Happy?

Wait, what?
Linux is ready for the desktop!
Of course, as this only affects 2.4 and 2.6, users of Debian stable should have no reason to worry.
See? All that testing is worth it after all!
Because we fix it when someone finally notices it after eight years and then hush up so no one will know we didn't notice it for eight years and then when someone notices that we didn't notice it for eight years and makes everyone aware of that we then try to minimize the impact by saying "We fix it instead of hushing it up until it becomes fairly well known and then waiting a month to fix it" instead of hushing it up until it becomes fairly well known and then waiting a month to fix it.
FTFY
nobody (the apache account) is a local user.
That nobody guy is really smart.
I often tell people that nobody is smarter than me.

But it wasn't a real "no true scotsman" fallacy. After all, it didn't involve a scotsman. :-)
The Tao of math: The numbers you can count are not the real numbers.
I broke into nobody's account and took a peek at their files. Look what I found:
