Microsoft has released an emergency patch to fix a critical vulnerability discovered in Internet Explorer.

"In a web-based attack scenario, an attacker could host a specially crafted website that is created to exploit the vulnerability through Internet Explorer and then convince a user to view the website, for example, by sending an email", Microsoft wrote.

Microsoft patched five escalation privilege flaws over the past four months-all of which were actively being exploited in the wild.

ZDNet's Mary J Foley notes that Windows Sandbox is available to users of Windows 10 Pro or Enterprise running Insider Build 18301 or later - a version not available at the time of writing but expected later in the week.

Today, we released a security update for Internet Explorer after receiving a report from Google about a new vulnerability being used in targeted attacks. IE9 (Windows Server 2008) and IE10 (Windows Server 2012) are also impacted.


The most popular way to put up some suspicious code running on a device is by tricking in the user to install a suspicious program on the targetted device. You can manually check for updates here. The Office app also provides shortcuts to our most recently used documents, pinned documents, and documents shared with you.
