Apple has released an emergency patch in iOS 12.4.1 that addresses a vulnerability that opened iPhones to jailbreaks. The flaw (CVE-2019-8605) could enable a malicious application to execute arbitrary code with system privileges in up-to-date iOS devices. A public jailbreak was released last week to take advantage of the flaw on phones running the latest version of iOS. Apple also released updates for iOS Mojave and tvOS addressing the kernel vulnerability in Monday’s update.
