Microsoft release emergency Windows 10 Cumulative Update due to Internet Explorer Zero-day vulnerability

Due to Microsoft’s legacy browser, Internet Explorer, you may need to reboot your PC soon.

Microsoft has released emergency patches for various versions of Windows following a Google security researcher finding a zero-day exploit in Internet Explorer.

Microsoft writes:

CVE-2018-8653 | Scripting Engine Memory Corruption Vulnerability

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.
