Linux Kernel Bug Found...and Quickly Fixed

Linux Kernel Bug Found...and Quickly Fixed

Although "trivially" fixable - and already fixed - a "kernel-crasher" bug was discovered by Øyvind Sæther, a young Norwegian programmer, earlier this week.

The exploit could be used, Sæther reported, to take down several "lame free-shell providers" servers. Stressing that hacking is an illegal activity in most parts of the world, Sæther posted several patches to 2.4 and 2.6 kernels designed to keep the exploit from crashing systems

Although the bug doesn't give an attacker any other control of a Linux system than crashing it, Linus Torvalds was fast to act and had already fixed it in his source code tree almost immediately and a 2.6.7 release of Linux patching the bug already went live at kernel.org earlier today.

Now THAT is hilarious. That vendor''s OS offerings are the security bane of our lives. Holey OS, Batman! I found *another* security flaw they''ll fix in a few months.

So the patch was available in no more than 4 days. In the proprietary world it can take more than four days for a lot of vendors just to look at the goddamn security/bug report
