Microsoft Rolling Out Emergency Patches To Compensate For CPU Flaws

Microsoft Rolling Out Emergency Patches To Compensate For CPU Flaws

Meltdown and Spectre are flaws in many microprocessors that attackers could use to steal kernel data, including passwords and encryption keys.

Microsoft says your antivirus software could stop you from receiving the emergency patches issued for Windows.

Warning: Microsoft Fix Freezes Some PCs With AMD ChipsMeltdown and Spectre Security Update Bricks Some PCs With Athlon CPUsMathew J. Schwartz (euroinfosec) • January 8, 2018 The view for users of some Windows PCs based on AMD chips after Microsoft's emergency Meltdown and Spectre security update gets installed.

By now Windows users should have received the patches Microsoft released yesterday to plug the widespread Meltdown bug and its companion Spectre, which expose most computers and phones to speculative execution side-channel attacks that affect chips from Intel, AMD, and Arm. Further exacerbating the issue, as The Register notes, is that the update doesn't create a restore point, leaving some users without a way to roll back to a pre-patched state.

Windows 10 Mobile Build 15063.850 is now rolling out to general users, though the update is being gradually rolled out.

If that wasn't enough, Microsoft also made two changes to its Edge and Internet Explorer browsers to mitigate potential exploits by attacks through JavaScript.

To avoid causing widespread BSOD problems Microsoft opted to only push its January 3 security updates to devices running antivirus from firms that have confirmed their software is compatible. Updates were issued for the Fall Creators Update, the Creators Update and the original version of Windows 10, although Insiders had many vulnerability fixes for a few months.

This update includes quality improvements.

Our readers confirmed that AMD systems lock up with the Windows logo showing on a black screen as soon as they update their computers.

The update's appearance still depends on the antivirus program that the user employs to protect the computer.

Those who have suffered from the putrid patch will therefore need to disable Windows Update as just about the first thing they do. One of the security researchers said the bugs are "going to haunt us for years". The result will be a more secure, but - as Linux creator Linus Torvalds says - slower operating system.
