Apple Releases iOS 11.2.2 And macOS 10.13.2 Security Updates To Counter Dangerous Spectre Exploit
"In the coming days we plan to release mitigations in Safari to help defend against Spectre," said Apple on Friday. "We continue to develop and test further mitigations for these issues and will release them in upcoming updates of iOS, macOS, and tvOS."
True to its word, Apple today released two new updates: one for iOS and one for macOS. iOS 11.2.2 brings further fortifications for the mobile operating system against the Spectre vulnerability, and is available right now to all supported devices (iPhone 5s and newer, iPad Air and newer).
The support document specifically states that "iOS 11.2.2 includes security improvements to Safari and WebKit to mitigate the effects of Spectre (CVE-2017-5753 and CVE-2017-5715)." Likewise, the macOS High Sierra 10.13.2 Supplemental Update uses similar language with regards to stamping out the Spectre threat.
In last week's update, Apple gave this guidance with respect to its Spectre patch:
The Spectre security update for iOS and macOS can be accessed by using the Software Update mechanism in the respective operating systems.
