    Apple has finally released an official statement on the company's mitigations status regarding the recently disclosed Meltdown and Spectre vulnerabilities.

    Without mincing words, the Cupertino-based company says that "all Mac systems and iOS devices are affected" by the two vulnerabilities.

    Apple says that mitigations against the Meltdown flaw, currently known to affect only devices using Intel CPUs, has been quietly deployed in iOS 11.2, macOS 10.13.2, and tvOS 11.2.

    Apple Watch is not affected by the Meltdown flaw, the company said.

    Intel's PR department has been trying its best to dispell rumors that Meltdown patches cause performance dips for its CPUs. According to Apple's engineers, there was no "no measurable reduction in the performance of macOS and iOS as measured by the GeekBench 4 benchmark, or in common Web browsing benchmarks such as Speedometer, JetStream, and ARES-6."

    No Apple product has patches to protect against the Spectre flaws but the company promised updates for iOS, macOS, tvOS, and watchOS.

    Nonetheless, the first product to receive Spectre patches will be Safari, on both macOS and iOS. The update is expected in the coming days.

    The hurry to patch Spectre on Safari comes from the fact that Spectre can be exploited via JavaScript code, just by accessing a website or viewing a malicious ad. Based on currently available information, Meltdown can't be exploited via JavaScript.
