It is highly advised for people using older iPhones or iPads to download the iOS 15.7.4 or iPadOS 15.7.4 update as it includes critical security patches.
iOS 15.7.4, iPadOS 15.7.4: What’s fixed
One of the most critical vulnerabilities the update addresses is a WebKit vulnerability that was already known to be actively exploited. WebKit is the browser engine used by Apple’s Safari browser, and the vulnerability could allow attackers to execute arbitrary code on a user’s device if the user visited a maliciously crafted website.
Moreover, the update addresses a vulnerability that could potentially exfiltrate user information through a maliciously crafted calendar invitation. The issue was caused by multiple validation issues that have now been addressed through improved input sanitization.
Another issue that the security update has addressed is related to the camera on the same older Apple devices. A sandboxed app could determine which app currently uses the camera and which malicious actors could exploit it.
The security update, iOS 15.7.4 and iPadOS 15.7.4, is available for several older Apple devices, as mentioned below.
