Google will release a new security update on January 5 that will help protect your Android Phone against Meltdown and Spectre.

SPECTRE MELTDOWN HOW TO

How to fix Meltdown and Spectre CPU security flaws on Android phones We’ll keep updating this list as new fixes emerge.

How to protect against the Meltdown and Spectre CPU security flawsīelow you’ll find ways to fix and protect yourself against the Meltdown and Spectre CPU security flaws for a range of devices.

So, don’t be too alarmed, but keep an eye on any updates your device offers, and follow our advice on how to protect against the Meltdown and Spectre CPU security flaws.

However, this does mean that future processors should be free from the Spectre and Meltdown security flaws. While it’s good to see companies set aside their differences to find a fix for these flaws, it has emerged that one flaw, Spectre, may need a processor redesign to fix. Intel has claimed that the exploits can't corrupt, modify or delete data. Should I be worried about Spectre and Meltdown?Īt the moment, you shouldn’t panic too much, because so far it doesn’t look like the Spectre or Meltdown flaws have been used in an attack, and device manufacturers are working with Intel, ARM and AMD to fix these flaws. Namely, it was revealed that they had been present in chip designs for over 20 years, and that they affect a number of companies’ processors, meaning the flaws could be found on a huge number of devices, from PCs to web servers and even smartphones. The flaws, found by a number of people including a member of Google’s Project Zero, are sending shock waves through the IT world. watchOS is unaffected by Spectre.Spectre and Meltdown are the names of the flaws found in a number of processors from Intel, ARM and AMD that could allow hackers to access passwords, encryption keys and other private information from open applications. We continue to develop and test further mitigations within the operating system for the Spectre techniques. On January 8th Apple released updates for Safari on macOS and iOS to mitigate such timing-based techniques. Testing performed when the Safari mitigations were released indicated that the mitigations had no measurable impact on the Speedometer and ARES-6 tests and an impact of less than 2.5% on the JetStream benchmark. Spectre is a name covering multiple different exploitation techniques, including-at the time of this writing-CVE-2017-5753 or "bounds check bypass," and CVE-2017-5715 or "branch target injection," and CVE-2018-3639 or “speculative bounds bypass.” These techniques potentially make items in kernel memory available to user processes by taking advantage of a delay in the time it may take the CPU to check the validity of a memory access call.Īnalysis of these techniques revealed that while they are extremely difficult to exploit, even by an app running locally on a Mac or iOS device, they can be potentially exploited in JavaScript running in a web browser. We continue to develop and test further mitigations for these issues. Apple Watch is not affected by either Meltdown or Spectre.

Since exploiting many of these issues requires a malicious app to be loaded on your Mac or iOS device, we recommend downloading software only from trusted sources such as the App Store.Īpple has already released mitigations in iOS 11.2, macOS 10.13.2, and tvOS 11.2 to help defend against Meltdown. Security updates for macOS Sierra and OS X El Capitan also include mitigations for Meltdown. To help defend against Spectre, Apple has released mitigations in iOS 11.2.2, the macOS High Sierra 10.13.2 Supplemental Update, and Safari 11.0.2 for macOS Sierra and OS X El Capitan. All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at the time of this writing. These issues apply to all modern processors and affect nearly all computing devices and operating systems. Security researchers have recently uncovered security issues known by two names, Meltdown and Spectre.
