Advanced Micro Devices, Inc. is an American multinational

|
|
|
|
|
semiconductor company based in Santa Clara, California, that develops
|
|
|
|
|
|
computer processors and related technologies for business and consumer
|
2020-07-30 14:34:56 +03:00
|
|
|

markets. This article is specifically about the CPUs that are
|
2020-07-25 12:33:15 +03:00
|
|
|
|
produced by AMD and nothing else. The logo is one of many logos used
|
|
|
|
|

by AMD, but the article is not about any one specific CPU.

Modern CPU models produced by AMD contain an embedded ARM co-processor
|
2020-07-30 14:34:56 +03:00
|
|
|
|
called the Platform Security Processor (PSP). Nearly all AMD CPUs
|
2020-07-25 12:33:15 +03:00
|
|
|
|
produced since 2013 operate under the supervision of this separate,
|
|
|
|
|
|
more privileged, environment consisting of an integrated ARM processor
|
|
|
|
|
|
with access to isolated resources as well as main system memory and
|
|
|
|
|
|
I/O.

While ARM and AMD tout the “Trusted Execution Environment” as useful
|
|
|
|
|
|
for secure payment, anti-theft and malware protection, they also
|
|
|
|
|
|
discuss content protection or DRM as a use case.

Researchers have already been able to identify exploits in AMD’s
|
|
|
|
|
|
Platform Security Processor. In 2018 researchers published a
|
|
|
|
|
|
vulnerability in which a specially crafted certificate could lead to a
|
|
|
|
|
|
stack overflow in the PSP’s TPM firmware allowing for remote code
|
|
|
|
|
|
execution. (https://seclists.org/fulldisclosure/2018/Jan/12) Another
|
|
|
|
|
|
group goes on to detail how an attacker might leverage exploits
|
|
|
|
|
|
RYZENFALL or FALLOUT to gain foothold in networks with Ryzen based
|
|
|
|
|
|
systems.
