Apple has released iOS 15.3.1 and iPadOS 15.3.1 firmware, which are required for installation. Apple says they contain "important security updates for your iPhone and iPad." In addition, the firmware also fixes an issue that could cause braille displays to stop working. To download and install the update, go to Settings General Software Update. The update size is 862.7 MB.
It's worth remembering that iOS 15.3 and iPadOS 15.3 included a fix for a Safari vulnerability that allowed attackers to track user visits on the Internet. The bug "allowed any website to track your internet activity and even reveal your identity," according to FingerprintJS. The latest update strengthens protection against this exploit.
The patch is listed under the heading WebKit and reads: "Available for: iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch ( 7th generation). Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware that this issue may have been actively exploited."
As for the upcoming iOS 15.4 update, the most anticipated feature is the ability to unlock your iPhone with Face ID while wearing a mask without using your Apple Watch. Apple is going to "use unique features in the eye area for authentication" instead of using full facial recognition. There's also a setting that will allow Face ID to recognize the user's facial features even if they're wearing glasses.
OS 15.4 will be released on March 8: the most interesting innovations are listed in our previous note.
