Apple released several important software updates for iPhone and Mac this week. Although you might not think so based on the version numbers of each update, iOS 17.4.1 and macOS 14.4.1 are both worth installing as soon as possible. Here’s why:
What’s new in iOS 17.4.1?
Apple’s latest update for the iPhone (and iPad) doesn’t include any new features or changes for users. Since the release notes don’t list any specific new changes, you might think it’s safe to skip or postpone the update.
However, as Apple’s security release notes make clear, it’s an important one. For some reason, the company packages its security notes separately from the release notes that appear in the software updates section of your device. In this case, the company even postponed his 17.4.1 security note until the release of macOS 14.4.1, which was released a few days later.
In any case, we know that iOS 17.4.1 (and iOS 16.7.7) patches two security vulnerabilities. The first is an out-of-bounds write flaw in CoreMedia, the part of iOS that handles time-based processing. audiovisual assets. A malicious attacker could exploit this flaw to trick a user into opening a malicious image, which could lead to arbitrary code execution. This means that they can exploit the flaw to execute their own code on the device and take control of it.
The second is another out-of-bounds write vulnerability. This time it’s about WebRTC, a platform that enables audio and video communication capabilities within a web browser. Again, processing a malicious image containing this flaw could allow someone to execute arbitrary code and take over the device.
At the time of publication, Apple was not aware that these vulnerabilities were being exploited, which is good news. However, these are more widely advertised and it’s only a matter of time before someone tries to use them, so it’s important to update them as soon as possible.
What’s new in macOS 14.4.1?
macOS 14.4.1 (and macOS 13.6.6 for that matter) also includes these two patches, which is likely why Apple waited to release these Mac updates before disclosing the specific vulnerabilities.
However, in addition to delivering important security patches, macOS 14.4.1 includes bug fixes for issues you may have encountered while using macOS 14.4. According to Apple’s release notes, this update fixes an issue where macOS would not recognize a USB hub when connected to an external display, and one bug where copy-protected Audio Unit plug-ins would not open or pass validation. It has been fixed. Perhaps most importantly, this update fixes an issue that could cause apps that use Java to close unexpectedly.
These three patches fix some of the issues that macOS users have reported with version 14.4, so if you were holding off updating to that version due to one of these three specific issues. macOS 14.4.1 is a safer choice.
How to update your iPhone or Mac
Whether your iPhone is running iOS 17 or iOS 16, or your Mac is running macOS Sonoma or macOS Ventura, you should update as soon as possible to patch these issues.
