Just seven days subsequent to carrying out significant updates for its operating systems, Apple has released patches for iOS, iPadOS, macOS and watchOS. The organization said in support documents that the updates settle WebKit imperfections that may have been abused. The issues concerned “maliciously crafted web content [that] may lead to arbitrary code execution.”

Among the issues were a memory corruption issue and integer overflow on macOS and iOS, and buffer overflow and use after free issues on older iOS gadgets. To determine the imperfections, Apple has released iOS 14.5.1, iPadOS 14.5.1, macOS Big Sur 11.3.1 and watchOS 7.4.1. Proprietors of older iPhones, iPads and iPod touch gadgets that don’t support recent versions of iOS can download and install iOS 12.5.3 instead.

Given that Apple believes the flaws might have been “actively exploited,” it’s a smart thought to install the updates as soon as possible.
