Intel CPU Privilege Escalation Exploit
A very interesting security concern quoted as being: "This is the scariest, stealthiest, and most dangerous exploit I've seen come around since the legendary Blue Pill!"
This seems to be related to the system firmware / BIOS code so the exploit will work on all systems. However, it needs root privileges to be possible.
Yet another reason to have FLOSS firmware / BIOS ... and not normally run a system as root.
Interesting information !
I use AMD since Athlon 1. And i wait for ARM notebooks. Any danger about these, related to Intel flaw ?
Anybody know if this is all intel CPU's or just certain ones (newer perhaps?). I don't suppose theres any fix to this kind of error.
Well it says:
So basically, a BIOS upgrade may fix it.
I don't know exactly the nature of the exploit as they don't do their best to use layman's terms or put it in ways normal people can understand. I fixed the original post as it seems this is a BIOS exploit.
Also, you need root privileges in order for such an attack to be possible ... so don't run as root.
Here's more recent article on it:
Supposedly it's easier to implement on Linux, because mtrr can be easily accessed as root. Thus, the exploit requires root privileges. And it requires a vulnerable mobo.
