This results in the processor having to rely on the microcode
to decipher this zombie load and in doing so, applications that are currently residing on the CPU cache can access another application's data.
We've already delivered the microcode
update for Variant 4 in beta form to OEM system manufacturers and system software vendors, and we expect it will be released into production BIOS and software updates over the coming weeks.
"As I shared January 22, we identified the root cause of the reboot issue affecting the initial Broadwell and Haswell microcode
updates," said Intel's Navin Shenoy.
"While Intel tests, updates and deploys new microcode
, we are making available an out-of-band update today, KB4078130, that specifically disables only the mitigation against CVE-2017-5715 -- 'Branch target injection vulnerability.' In our testing this update has been found to prevent the behavior described."
Processor maker Intel, has said it wants customers to know that it's sticking to its recent commitment to put security first after it confirmed that it's investigating an issue with the CPU microcode
updates it issued to its hardware partners.
Seven parts of the textbook focus in turn (but not in order) on the seven levels of abstraction that computers operate at: application, high-order language, assembly, operating system, instruction set architecture, microcode
, and logic gate.
In the first step, line card architects use an intuitive, C-like high-level language (rather than arcane microcode
) to design the requirements and create a specification for a network line card.
Besides avoiding disruptions, the resulting intelligence about the storage infrastructure availability during peak periods also dramatically accelerates the time needed to diagnose and fix the kind of problems that are not predictable such as faulty fibre connections or other hardware or microcode
failures, untested application changes, unpredictable workload spikes, etc.," explained Brent Phillips, IntelliMagic Managing Director for the Americas.
This platform is based on one programmable broadcast-specific vector signal processor (VSP) and it is able to handle any TV standard by adapting its microcode
, the company added.
The modern computers contain a microcode
which is remotely updated by the security updates.
The 7-digit microcode
obtained from the scoring of positive tests before and after the addition of kit reagents was checked in the electronic RapID compendium ERIC(R) (http://www.remel.com/ERIC/IdentificationSingle.aspx) for the identification of the test organisms.
