HPSBHF03593 rev. 1 - Firmware Trusted Platform Module (fTPM) for Select AMD Client Systems

[Bill_1944]

I have a Pavilion 23-23-p027c all-in-one system with an intel processor. The Critical Security Bulletin - Sep 28 2018

(HPSBHF03593 rev. 1 - Firmware Trusted Platform Module (fTPM) for Select AMD Client Systems (c06154544)) references AMD client systems.

I have an Intel processor. Does this apply to me? The preperation for the update is complicated enough that I dont want to do it and see a message stating this does not apply to my system.

Thank you.

Short answer: NO, since AMD and INTEL are competitors.

I have desktop 550-140T with Intel processor  

Tried to get in touch with support but says they are down. 
Does this same critial update (HPSBHF03593 rev. 1 - Firmware Trusted Platform Module (fTPM) for Select AMD Client Systems (c06154544)) references AMD client systems.  

effect me? 

I tried to follow directions on it but only got something saying Ctp module cannot be found.

Same answer: NO, because you have an INTEL processor, not an AMD processor.

That's what I thought but wanted to be sure. Thank you.

That was my reasoning. However I thought HP might have different model numbers if there were different CPUs on the mother board. Also, AMD makes more chips than CPUs so it it still migt have been relevant. Would have been nice if they had said it id not apply to PCs with Intel processors.

There are many computers for which that update does not apply, even including some with AMD processors.

Example: some Apple computers have Intel processors, and some users "wipe" the Apple Operating System, and install Windows.

So, do you think that HP should have listed such a "bastardization" as being "not vulnerable" ?

In pseudo-code, assuming that the function:  Position(needle,haystack) 

exists, and returns '0' when the "needle" is not found,

or returns a positive number when the "needle" is found,

If Position(Processor_Type(),'AMD') > 0 then ,

Then If Position(Processor_model(), full_list_of_vulnerable_models) > 0 ,

Then Say 'Your AMD processor is vulnerable';

Else Say 'Your AMD processor is not vulnerable';

Else Say 'Your non-AMD processor is not vulnerable';
