Apple, Google and Microsoft release patches for ZombieLoad chip flaws

Big tech is stepping in to patch newly disclosed security flaws affecting almost every Intel chip since 2011.
Researchers on Tuesday released details of the vulnerability, known as ZombieLoad — or microarchitectural data sampling as its technical name — which can leaked sensitive data stored in the processor, such as passwords, secret keys and account tokens and private messages.
You can read our coverage here. In short, don’t panic — but you should patch your systems. Here’s how.

Apple released macOS fixes


Apple has fixes out for every Mac and MacBook released during and after 2011.
The tech giant said in an advisory that any system running macOS Mojave 10.14.5, released Monday, is patched. This will prevent an attack from being run through Safari and other apps. Most users won’t experience any decline in performance. But some Macs could face up to a 40 percent performance hit for those who opt-in to the full set of mitigations.
The security update will also be pushed to Sierra and High Sierra versions. iPhones, iPads and Apple Watch devices aren’t affected by the bugs.

Google patches Android, will update Chrome


The search and browser maker also confirmed it has released patches to mitigate against ZombieLoad.
Google said the “vast majority” of Android devices aren’t affected but Intel-only devices will need to be patched once device makers make updates available
Chrome OS devices, such as Chromebooks, are already protected in the latest version and permanent mitigations will be pushed to devices in the next version.
And, the company’s Chrome team has a technical advisory out but said users should rely on patches for their computer. “Operating system vendors may release updates to improve isolation, so users should ensure they install any updates and follow any additional guidance from their operating system vendor,” said Google. In other words, make sure your Windows PC or your Mac is patched.
Google also rolled out patches to its datacenters, so cloud customers are already patched but should be aware of the company’s guidance.

Microsoft rolls out Windows updates


Microsoft has released patches for its operating system and cloud.
Jeff Jones, a senior director at Microsoft, said the software and cloud giant has been “working closely with affected chip manufacturers to develop and test mitigations” for its customers. “We are working to deploy mitigations to cloud services and release security updates to protect Windows customers against vulnerabilities affecting supported hardware chips,” he said.
In a TechNet article, the company said customers may need to obtain microcode updates for their processor directly from their device maker. Microsoft is pushing many of the microcode updates itself through Windows Update, but are also available from its website.
Software updates will be released Tuesday also through Windows Update. Microsoft also has a page with guidance for how to protect against the new attacks.
Microsoft Azure customers are already protected, the company said.
Amazon and Mozilla did not return a request for comment. We’ll update if we hear back.
