Mitigating speculative execution side-channel attacks in Microsoft Edge and Internet Explorer

Today, Google Project Zero Microsoft Support Phone Number published  Support.Microsoft.Com/Help details of a  class of vulnerabilities which uninstall microsoft edge can be exploited by speculative execution side-channel attacks Microsoft Customer Service. These techniques can be used via JavaScript code running in the browser , which may allow attackers to Microsoft Customer Service gain access to memory in the attacker’s process .

Microsoft has issued security updates  with mitigations for this class of attacks. As part of these updates, we are making  changes to the behavior of supported versions of Microsoft Edge and Internet Explorer 11 to mitigate the ability to successfully read memory through this new class of side-channel attacks.

Initially, we are removing support for SharedArrayBuffer from Microsoft Edge (originally introduced in the Windows 10 Fall Creators Update), and reducing the resolution of performance.now() in Microsoft Edge Support.Microsoft.Com/Help and Internet Explorer from 5 microseconds to 20 microseconds, with variable jitter of up to an additional 20 microseconds uninstall microsoft edge. These two changes substantially increase the difficulty of successfully inferring the content Microsoft Customer Service of the CPU cache from a browser process.

We will continue to Microsoft Support Phone Number evaluate the impact of the CPU vulnerabilities published today, and introduce additional mitigations accordingly in future servicing releases.  We will re-evaluate SharedArrayBuffer for a future release once we are confident it cannot be used as part of a successful attack.

We made significant improvements Support.Microsoft.Com/Help to the Microsoft Edge DevTools in Edge with the Windows 10 Fall Creator’s Update uninstall microsoft edge, including new support Microsoft Customer Service for Dom mutation breakpoints and event and CSS inspection in the new elements tab..

Today, we’d like to walk through new improvements we’ve made to the Console to improve the output and input experiences of working with the Console. Our main goals were to increase the flexibility of the Console in displaying Microsoft Customer Service information, and to increase your productivity when working with the Console prompt.

First, let’s cover the new features we made to improve the user experience of Console output.

Log message consolidation and UX improvements

Have you ever written a console.log statement in a for loop and watched your entire Console fill up with output? Or have you found it Microsoft Customer Service difficult to easily spot the differences between warnings, info, and Microsoft Customer Service errors without uninstall microsoft edge having to resort to using filters?

To help address issues like these Microsoft Support Phone Number, we’ve updated the Console output to better differentiate between console message types. In addition Support.Microsoft.Com/Help, the Console will now consolidate repeated messages Microsoft Customer Service.
