Tap on the Windows-key, type PowerShell, hold down the Shift-key and the Ctrl-key and select the PowerShell entry to load it. Microsoft created a PowerShell script that returns whether your Windows PC is still vulnerable or if you don't have to worry about the vulnerabilities at all. Google will patch Chrome when Chrome 64 gets released on January 23, 2018.
Mozilla released a fix for Firefox 57, and patches for the latest versions of Edge and Internet Explorer are available already as well. It is required however that hardware firmware and other software programs are updated as well to protect against the vulnerabilities. Microsoft released an operating system update yesterday to address the issue. Research papers are linked on the website as well.Īffected are processors from Intel, AMD, ARM as well as operating systems and other software programs. Both vulnerabilities are described on the official Meltdownattack website. The first two variants, "bounds check bypass" and "branch target injection" go under the name Spectre, the last, "rogue data cache load," under the name Meltdown. The researchers that found the bug identified three variants of it. What this means is that attackers may read the memory of computer systems to steal passwords and other sensitive data. Meltdown and Spectre are designed vulnerabilities in modern processors that allow attackers to read virtual memory arbitrarily.
