As is typically the case in-between Patch Tuesdays, Microsoft released a bunch of optional cumulative updates today. The new updates are for all supported version of Windows 10, which is all of them except for version 1511.
There also isn't a whole lot that's new, with each changelog only saying that they have security updates for Internet Explorer. Here's the full description of the vulnerability that was fixed:
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.
And specifically, here are the updates that were released today:
- 1903: KB4522016 (build 18362.357)
- 1809: KB4522015 (build 17763.740)
- 1803: KB4522014 (build 17134.1009)
- 1709: KB4522012 (build 16299.1392)
- 1703: KB4522011 (build 15063.2046)
- 1607: KB4522010 (build 14393.3206)
- 1507: KB4522009 (build 10240.18334)
As mentioned above, these updates are optional, meaning that they won't automatically install on your machine like they would on Patch Tuesday. You'll need to get them through the Microsoft Update Catalog.
