A new and urgent (such is the nature of the beast) Rapid Security Response update has gone out across Apple devices. The patch is specifically for iOS 16.5.1, iPadOS 16.5.1, macOS Ventura 13.4.1, and Safari’s 16.5.2 web browser on Mac. As Apple’s changelog shows, this new security update addresses the same issue across all platforms: a WebKit exploit (CVE-2023-37450) that might have been used previously — meaning at some point, someone may have exploited the vulnerability with nefarious intent.
The exploit in question provided an opportunity for attackers to implement arbitrary code execution (ACE), which would allow them to perform functions and commands on an affected system without the owner’s knowledge or permission. Apple hasn’t provided details on what exactly this exploit may have been used for, but ACE vulnerabilities are pretty serious business. Because of this, it’s recommended that you download and install the new Rapid Security Response update as soon as possible.
Downloading the new updates
Updating your iPhone, iPad, or Mac with the latest security patch is, thankfully, very simple — though in all cases it will require a restart once the download is complete, so if you’re in the middle of something important, make sure to either finish first or save and quit so you can come back to it once everything is installed.
On iPhone and iPad:
- Open Settings.
- Select General.
- Tap Software Updates.
- Once the iOS Security Response 16.5.1 (a) update appears, tap Download and Install to begin the update.
On a Mac:
- Click the Apple icon in the top-left corner.
- Select System Settings.
- Select General.
- Select Software Update.
- Wait for your Mac to find the new 13.4.1 (a) update.
- Click the Update Now button to begin the installation.
Don’t worry about manually updating Safari on your Mac. Installing the security update for macOS will also take care of Safari at the same time.
