Updates released by Apple on Monday for iOS, macOS and Safari should mitigate the effects of the vulnerabilities exploited by the recently disclosed attack method named Spectre.
Apple informed customers that iOS 11.2.2 and macOS High Sierra 10.13.2 Supplemental Update include security improvements for Safari and WebKit. The Safari improvements are also included in version 11.0.2 of Apple’s web browser.
The latest updates address the Spectre vulnerabilities, specifically CVE-2017-5753 and CVE-2017-5715. Mitigations for the Meltdown attack were rolled out by Apple, before the flaws were disclosed, with the release of iOS 11.2, macOS 10.13.2 and tvOS 11.2. Apple Watch is not vulnerable to either of the attack methods.
