Apple updates iOS, macOS and Safari after the failure of security processors

Technology companies continue to respond to the two major security flaws, Meltdown and the Spectre, which affect almost all processors made in the last 20 years. This time, Apple is being pronounced.

The Apple is direct: “all Mac systems and iOS devices are affected”. So, it is releasing updates for their operating systems, and for the Safari, in order to mitigate the problem.

The technical Meltdown allows you to access the reserved memory to the operating system kernel, which has greater permissions. Apple says: “our analysis suggests that it has the most potential to be explored”.

It is believed that only Intel processors are affected. Still, she released the mitigations in iOS 11.2 and tvOS 11.2, in addition to macOS 10.13.2. “The Apple Watch is not affected by the Meltdown,” according to the company.

The fear is that these solutions reduce the performance, but Apple says that this does not happen. There was no “measurable reduction in the performance of macOS and iOS, as measured by the benchmark GeekBench 4, or on benchmarks common to web browsing, such as Speedometer, JetStream and ARES-6”.

In turn, the Spectre allows an application to leak sensitive information to another application. Apple says that this technique is “extremely difficult to exploit” applications macOS and iOS, but can be used in the browser through JavaScript.

Therefore, Safari for macOS and iOS will be updated in the next few days. As for the performance, it “will not have an impact measurable in the tests, Speedometer and ARES-6, and will have an impact lower than 2.5% in the benchmark JetStream”.

Microsoft has already released a patch emergency for the Windows and for devices Surface. Meanwhile, Google has detailed the updates in Android, Chrome and Chrome OS, to mitigate these problems.
