Apple just recently released another software update, iOS 16.3.1, which provides users additional security patches, as well as fixes a security breach that was “actively exploited.”

The new security update is now available for download for all users. To get the latest security patches, users of iPhone 8 and later, iPad Pro (all models), iPad Air 3rd generation and later, iPad 5th generation and later, and iPad mini 5th generation and later are encouraged to download the update.

The update includes a “maliciously crafted certificate” fix, which can improve input validation, and prevent a denial-of-service (DoS) attack. Through this fix, attackers are prevented from flooding the device or network with traffic in order to cause a crash.

The iOS 16.3 security content webpage was also updated with three new exploits that were fixed with this update. An app may potentially be able to execute arbitrary code with certain elevated privileges or outside of its sandbox, but the issue is addressed with improved memory handling.

In addition, there is an exploit that was found in the system’s Crash Reporter; it could have let attackers read arbitrary files as root. Two other Foundation-related exploits could have also put iPhones and iPads at risk as it could have potentially let attackers execute arbitrary code on the device with higher privileges.

Though Apple did not background information about these exploits prior to the update, it’s essential to keep track of any new security updates from the company to help protect yourself from any potential cyber attack. Apple’s website provides additional information on the security content of its software.

Are you up to date with your devices’ security updates? It’s important that you make sure to stay on top of the update releases, as these software can help prevent malicious cyber attacks. Share with us in the comments what you think of the new security patch and iOS 16.3.1 update!
