In the early hours of this morning, Apple pushed the update of the official version of iOS 15.3 for the majority of iPhone users, we just need to open the settings - universal - software update, and the online OTA upgrade to the latest iOS 15.3 official version.
The size of this official update package is about 970M, the version number of the update is (19D50), according to Apple's official update instructions, the official version of iOS 15.3 contains bug fixes and security updates for the iPhone, and it is recommended that all users install it.
It should be noted that since the version number of the iOS 15.3 official version is inconsistent with the version number of the iOS 15.3 RC version pushed last week, it also means that users who have updated to the iOS 15.3 RC version last week can also receive the update push of the iOS 15.3 official version and the online OTA upgrade as long as the iOS 15 beta version description file is deleted.
Although the version numbers vary, they are almost identical in the content of the update. Judging from the update feedback of fruit fans, the official version of iOS 15.3 does not have new features added, mainly to fix bugs.
According to a previous report by MacRumors, there is a bug in the Safari browser that comes with the iPhone, which allows any user who uses the IndexedDB website to access the name of the IndexedDB database generated by other websites during the browsing session.
But under normal circumstances, the database name of each website is usually unique, and users can only access their own IndexedDB database. But the vulnerability could allow a website to track other websites visited by a user, meaning that the vulnerability could reveal a user's browsing history at Safari and even expose the user's identity. Since the vulnerability exists in the open source engine WebKit, it also means that all Safari browsers that use apple's open source engine WebKit will be affected, including Safari 15 in mac OS and Safari browser in iPadOS 15.
At present, Apple has fixed this vulnerability in the latest iOS 15.3 official version, if you are worried about your iPhone affected by the vulnerability, you can upgrade to the latest iOS 15.3 official version.
In addition to the official version of iOS/iPadOS 15.3, Apple today also released updates to watchOS 8.4, macOS Monterey 12.2 and HomePod 15.3.
Among them, watchOS 8.4 official version fixed a bug, which can cause some third-party chargers to fail to charge the Apple Watch; macOS Monterey 12.2 official version is also a bug fix for Safari browser; HomePod 15.3 is a new English (Indian) and Italian (Italian) Siri speech recognition, supporting the recognition of up to six users in a home.
