After trying to patch an actively exploited WebKit flaw with a buggy update, Apple tries again to disseminate the required updates.
Back on June 21st, Apple disseminated iOS 16.5.1 and iPadOS 16.5.1. But soon it was discovered that the updates had a flaw in the WebKit browser engine that could lead an attacker to create an arbitrary code execution which would allow said attacker to run any command or code on a targeted device. That is a serious problem and to top it off, Apple said that it had reports that the vulnerability was being actively exploited.Instead of having to develop iOS 16.5.2 and iPadOS 16.5.2, Apple decided to use its Rapid Security Response feature to push out iOS 16.5.1 (a) and iPadOS 16.5.1 (a). These updates can be installed in a matter of minutes and can be quickly disseminated to Apple device users to patch a serious vulnerability such as the one that was supposed to be patched by Monday’s update.
