[morbondu]

so whats the deal with the linux kernel bug thing? exactly how would a local attacker mess up my kernel or gain root access?

 

any ideas?

to put it simple there's an overflow in part of the kernel code that handle memory. So if i write an exploit to attack that section of code and send too much info into that variable the function can't handle it and for the most part might crash. From there, the attacker can access any part of the system's memory. And generally there are some /bin/sh processes running that can be taken over. Then you have root access.

 

Thats making it as simple as possible. I could explain it a lot better but i'm horribly sick and sitting at work.
