CPU vulnerability. Other software Several procedures to help protect home computers and related devices from the vulnerability have been published. Initial mitigation efforts were not entirely without incident. At first, Spectre patches were reported to significantly slow down performance, especially on older computers. On the newer eighth generation Core platforms, benchmark performance drops of 2–14 percent were measured. On 18 January 2018, unwanted reboots were reported even for newer Intel chips. Since exploitation of Spectre through JavaScript embedded in websites is possible, it was planned to include mitigations against the attack by default in Chrome 64. Chrome 63 users could manually mitigate the attack by enabling the Site Isolation feature (chrome://flags#enable-site-per-process). As of Firefox 57.0.4, Mozilla was reducing the resolution of JavaScript timers to help prevent timing attacks, with additional work on time-fuzzing techniques planned for future releases. On January 15, 2018, Microsoft introduced mitigation for Spectre in Visual Studio. This can be applied by using the /Qspectre switch. A developer would need to download and install the appropriate libraries using the Visual Studio installer.
