Apple today released tvOS 12.4.1, watchOS 5.3.1, and macOS Mojave 10.14.6 for its Apple TV, Apple Watch, and Mac devices, to go along with an iOS 12.4.1 update that addresses a serious vulnerability which made it possible to jailbreak many recent iPhone models running iOS 12.4.
Apple actually addressed the vulnerability in iOS 12.3, but then accidentally unpatched it in the iOS 12.4 update.
Available for: iPhone 5s and later, iPad Air and later, and iPod touch 6th generation
Impact: A malicious application may be able to execute arbitrary code with system privileges
Description: A use after free issue was addressed with improved memory management.
CVE-2019-8605: Ned Williamson working with Google Project Zero
The patch is available through the iOS Settings panel and like all updates rolls out gradually over an hour or two. Patches for tvOS 12.4.1 and watchOS 5.3.1 are also available.
On the Mac, the update fixes several issues:
This update:
– Resolves an issue that may cause certain Mac notebooks to shut down during sleep
– Fixes an issue that may degrade performance when working with very large files
– Addresses an issue that may prevent Pages, Keynote, Numbers, iMovie, and GarageBand from updating
It is good to see Apple taking quick action towards fixing such serious issues.
