Subject description: for all 2.4 & 2.6 kernels
 

Quote:
This is a serious bug, it effects all Kernel versions released since May 2001! That goes all the way back to the early 2.4 versions.

It’s also exploitable according to the report – This issue is easily exploitable for local privilege escalation. In order to exploit this, an attacker would create a mapping at address zero containing code to be executed with privileges of the kernel (which I would assume to be root).

At least it only allows local priveledge escalation, if was a remote root exploit in the kernel..it would be a disaster.

A patch has been released, so if you have untrusted local users on your system UPDATE YOUR KERNEL NOW!

This is the second time this year there has been a serious exploit in the Linux Kernel, which in a way is good because it means people are looking at it critically.

The more bugs that get exposed, the more secure the Kernel and our operating systems become.

I heard about this at Slashdot. Puppy users are already the most "privilidged" in linux-space, we run as root all the time. Would it effect, and how would it effect, Puppy users?
