Oracle issues security patches for chip flaws

Intel last week acknowledged that firmware updates meant to mitigate the security threats posed by Meltdown and Spectre were causing reboot issues in both client and data center computers powered by Broadwell and Haswell processors. So devices that have updated their OS should be protected.

Computer experts warned that could give an intruder access to all kinds of sensitive information including passwords, log-in information, or cached files.

The speculative execution vulnerability is one of the most significant processor security flaws ever discovered, because it affects so many types of consumer electronic devices.

It also affected Kaby Lake chips - its most recent offering. If you have patched Meltdown and Spectre vulnerabilities on Intel systems and your PC has got substantially slower, you're not alone.

Merchants with semi-integrated solutions that don't store data have greater protection from these chip flaws, but merchants' systems vary widely, he noted.

However, numerous patches released appear to have had a highly deleterious effect on CPU performance, with Microsoft last week confirming that its Variant 2 of Spectre could have "significant performance impact," on some systems, especially those running Windows 7 or Windows 8 on older silicon. The Meltdown and Spectre bugs were privately disclosed to the chipmakers in June of past year, but the issues became public after a series of leaks earlier this month. However, if you're running Windows 7 on an old computer, chances that you may experience performance problems and computer slowdowns are pretty high.

Our comparisons are based on two catch-all benchmarks.

"We measure the time of trades in microseconds". But there are also instances where performance is more adversely affected.

Intel released a statement recommending users "check with your operating system vendor or system manufacturer and apply any available updates as soon as they are available".

Crisis PR textbooks will be written about Intel's response to the Meltdown and Spectre flaws, which compromise the security of almost every Intel-powered computer built over the last 20 years. With a 70/30 read/write model, there was a 2% decrease in throughput performance. You can download this app on Gibson Research's website. The HP EliteBook 1040 G4 dropped by 44 points, to 3,510. It now says the patch is having a similar effect on newer processors.
