Apple patches two iOS zero-days in old-gen devices
Apple has released today security updates to address two zero-day vulnerabilities that were exploited in the wild to hack older generation iPhones and iPads.
Both vulnerabilities, tracked as CVE-2021-30761 and CVE-2021-30762, reside in WebKit, the browser engine used by Safari, and the component used by all iOS apps to load web content.
Apple said it received reports from anonymous researchers that threat actors had exploited the two bugs to run malicious code on users’ devices when the WebKit engine loaded and processed maliciously crafted web content.
The Cupertino-based company released today iOS 12.5.4 to patch both issues.
The update is intended for old-gen devices such as the iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation), Apple said.
The two zero-days patched today mark the 8th and 9th actively-exploited zero-days patched in Apple products this year. Previous zero-days included:
