Apple has released a hotfix security update to fix a bug in the engine WebKit of your browser, Safari. However, Apple then withdrew the update due to problems encountered in browsing some websites, which was slower than it should be.
Apple releases and then retires WebKit update
For some time now, Apple has introduced rapid security updates, which allow you to intervene when there are risks. To ensure user protection, the option to automatically apply quick fixes is enabled by default on Apple devices (although you can remove it by going to “Settings” > “General” > “Software Update” > “Automatic Updates”).
The bug that prompted Apple’s quick fix affects the WebKit browser engine developed by the company itself. This engine is used not only from Safari, but also from all third-party browsers that can be installed on iOS and iPadOS. The vulnerability allowed for the execution of arbitrary code on target devices by exploiting visits to web pages containing malicious elements.
Apple then released the security hotfix to address this. However, after the release, problems have arisen in browsing some websites, which have led to the immediate withdrawal of the update. This is because it seems there were slowdowns while browsing.
Some employees have reported difficulty logging into site like Facebook, Instagram and Zoom. It’s not clear what the reason is, however it seems likely that Apple will soon release a solution that brings security without sacrificing functionality.
