Webkit flaws in just-released iOS 14.5 lets attackers execute malicious code.
DAN GOODIN - 5/3/2021
A week after Apple issued its biggest iOS and iPadOS update since last September’s release of version 14.0, the company has released a new update to patch two zero-days that allowed attackers to execute malicious code on fully up-to-date devices. Monday’s release of version 14.5.1 also fixes problems with a bug in the newly released App Tracking Transparency feature rolled out in the previous version.
Both vulnerabilities reside in Webkit, a browser engine that renders Web content in Safari, Mail, App Store, and other select apps running on iOS, macOS, and Linux. CVE-2021-30663 and CVE-2021-30665, as the zero-days are tracked, have now been patched. Last week, Apple fixed CVE-2021-30661, another code-execution flaw in iOS Webkit, that also might have been actively exploited.
