Microsoft delivers an out of band Windows 10 Cumulative Update to fix Internet Explorer vulnerability

Microsoft has released an out of band Cumulative Update for all supported versions of Windows 10 which addresses a new Remote Code Execution Internet Explorer vulnerability.

Microsoft describes the serious bug as follows:

A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

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

The security update addresses the vulnerability by modifying how the scripting engine handles objects in memory.

The bug is thankfully currently not wormable and Microsoft has released the following updates for each supported version of Windows 10. Microsoft will likely push out the updates automatically during next month’s Patch Tuesday but if you are concerned you can download and install them early from the links below:
