If I had a C2D I would try to get my money back and when the next line of fixed CPU's come out get one of them.
..ROFL!

I love how all the AMD fanboys jump all over this while:

1. I guarantee you can't explain the problem to me.
2. It's no big deal.
->agreed...those chumps, cant stand to see blood in the water...makes them nervous, its a 'preys' natural instinct.

You're right, I'm sooooooooo afraid that my system will be comprimised after ~ 1 year of flawless performance.
Maybe after two years of buggy glitches freezing and restarting my cpu, its performance will suck as bad as an AMD x2...then I'll be right on-par! Wait does that mean, that my Q4 is going to suck like two X2's put together...oh noooes! [i doubt it..going on one year straight 24/7 use at 3.8ghz w/ the e6700....no issues here]
------------------ One last thing to remember folks....
*Its a COMPUTER...it IS exploitable. Its man made and runs code...written by chimpanzees...what did you expect it was going to work ..perfect. LMAO

Good report to hype all the crazies up about nothing though.

Does that include all the CPU based on Core 2 Microartitechure?


Good thing I haven't got a Conroe yet.

Its a farce! all computers are H4X4BLE! Dont let the fan boy's, get you down.

Besides all this means is that Intel is going to slash prices even more, selling their 'corrupted C2D's' for 100x less than an AMD sempron...forcing AMD that much farther into the stone age. The guy that discovered this so-called problem, is probably on the payroll for AMD...LOL

The chances of someone with the proper programming knowledge coming along and exploiting your CPU at random are about 1 in 1,000,000,000,000,000. This is nothing the end user has to worry about, especially if they don't run any type of public hosting or services.

End user, such as ourselves, nothing to worry about.

Data processing companies and engineers, plenty to worry about.

LoL This thread is retarded.

My computer runs fine. Leave it up to people using ANYTHING against something they don't like to keep it going FIVE pages.

And not a SINGLE POST explains "I understand what this does"; way to go, team!

Way to read my post that explains what it does.

AI65

When the temperature reaches an invalid temperature the CPU does not generate a Thermal interrupt even if a programmed threshold is crossed.

I don’t see how this is a security concern; maybe he meant AI56, which gives unpredictable behavior if you change the attributes of a PTE without fixing up the TLB; AI64 involves system management mode and AI67 involves VTX.
AI79

During a series of REP (repeat) store instructions a store may try to dispatch to memory prior to the actual completion of the instruction. This behavior depends on the execution order of the instructions, the timing of a speculative jump and the timing of an uncacheable memory store. […] When this erratum occurs, the processor may live lock and/or result in a system hang.

Unless the behavior depends on system memory inaccessible to userland, this could imply userland crasher exploit.

AI43

When a logical processor writes to a non-dirty page, and another logical- processor either writes to the same non-dirty page or explicitly sets the dirty bit in the corresponding page table entry, complex interaction with internal processor activity may cause unpredictable system behavior […] and hang.

Two userland processes on two different cores can race each other and hang the system?

AI39

When request for data from Core 1 results in a L1 cache miss, the request is sent to the L2 cache. If this request hits a modified line in the L1 data cache of Core 2, certain internal conditions may cause incorrect data to be returned to the Core 1.

Where the word “incorrect data†is errata code for “Zuul’s return as the Sta-Puft Marshmellow Man†—- two cores race each other, and a process gets the wrong cache line.

AI90

If code segment limit is set close to the end of a code page, then due to this erratum the memory page Access bit (A bit) may be set for the subsequent page prior to general protection fault on code segment limit. […] a non-accessed page which is present in memory and follows a page that contains the code segment limit may be tagged as accessed.

Theo says this is exploitable on operating systems other than OBSD; the A bit signals the VM system that a page has been accessed by the hardware.

AI99

Code #PF (Page Fault exception) is normally handled in lower priority order relative to both code #DB (Debug Exception) and code Segment Limit Violation #GP (General Protection Fault). Due to this erratum, code #PF may be handled incorrectly, if all of the following conditions are met:

*

A PDE (Page Directory Entry) is modified without invalidating the corresponding TLB (Translation Look-aside Buffer) entry
*

Code execution transitions to a different code page such that both:
o

The target linear address corresponds to the modified PDE
o

The PTE (Page Table Entry) for the target linear address has an A (Accessed) bit that is clear
*

One of the following simultaneous exception conditions is present following the code transition:
o

Code #DB and code #PF
o

Code Segment Limit Violation #GP and code #PF

Software may observe either incorrect processing of code #PF before code Segment Limit Violation #GP or processing of code #PF in lieu of code #DB.
