Apple releases iOS 15.3 with important security fix


Apple released this Wednesday (26) iOS 15.3, a few days after putting the Release Candidate versions in the hands of testers. On iPhone, the build is identified by the number 19D50, on iPadOS, it is 21D49. watchOS 8.4 (19S546), tvOS 14.3 (19K547), and macOS Big Sur 11.6.3 (20G415) have also been released for the supported devices.

Included in the update are fixes for the IndexedDB API vulnerability found in Safari and rival browsers. The resource stores data from pages accessed to aid navigation, however, in the most recent versions of the system, this information was not restricted to the domain of origin, allowing other pages to capture this data.

Due to the scope of the issue, it affected popular platforms such as Netflix, YouTube, Alibaba, Twitter, Google and Dropbox. Such an inconvenience forced Apple to act quickly on the solution.

Apparently, the update doesn’t introduce any new features to the operating system — which is bad news for anyone expecting big news like Universal Control. However, even if it does not introduce anything new, it is important to update the system to ensure more security in internet browsing.

The update should be distributed to all devices automatically, as usual. Keep an eye on system notifications to download the package as soon as it is available on your device.
