Update your Mac and iPhone immediately — Apple aware of security vulnerability that ‘may have been exploited’, now patched in iOS 17.3, macOS 14.3
Apple has just issued a major software update to several of its main product lines that patches a security vulnerability the company says may have been exploited in the wild.
It comes as the company released its latest version of iOS 17, 17.3 alongside iPadOS 17.3, and macOS Sonoma 14.3 on Monday, alongside new versions of tvOS and watchOS 10. Given it’s a major update most of them bring some new features to your Apple devices, including an important Stolen Device Protection feature on iPhone, collaborative Apple Music Playlists, and a new Apple Watch Face.
However, nearly all updates for iOS and beyond come with important security updates, and this week’s stable is no exception.
iOS 17.3’s important security update
Apple says it has patched security issues in the Apple Neural engine on iPhone and iPad, Safari, Shortcuts, and more. The most important one is the third of three WebKit updates, all of which fix exploits that could have led to “arbitrary code execution.” Apple says that this particular WebKit involved “Processing maliciously crafted web content may lead to arbitrary code execution,” which essentially means an attacker taking control of your Mac or iPhone.
Apple says it is “aware of a report that this issue may have been exploited,” suggesting bad actors might have already used this exploit to try and hijack devices, take data, and more. “The bug in WebKit causes the framework to malfunction when processing specific content it is not expecting, such as a corrupted image file,” security experts Mysk told iMore. “In this case, the malfunctioning caused by the bug opens a security hole where an attacker can trick the framework into executing malicious code and gain access to protected resources on the system.”
While it’s always a good idea to keep your iPhone bang up-to-date for security purposes, this is yet another example of a particularly important security update that you don’t want to put off.
To download iOS 17.3:
The update is available for all of Apple’s best iPhones including the iPhone 15 and iPhone 15 Pro, and on older models up to and including the iPhone XS.
As noted, Apple says this issue is also present in macOS Sonoma, and as such has been patched in macOS 14.3, which can be downloaded from your System Settings on Mac.
