Windows' Built-In PDF Reader Exposes Edge Browser To Hacking (softpedia.com)
An anonymous reader writes: Edge, Microsoft's new browser, uses the WinRT PDF library to automatically embed and present PDF files while navigating the web. This is what Java does with applets, and Flash with SWF files -- it unintentionally allows a hacker to append malicious code to PDF files and trigger drive-by attacks, which exploit WinRT vulnerabilities to target Windows 10 users. All that an attacker needs to do is to find and create a database of WinRT vulnerabilities it could leverage to distribute his malware.
This. My company gave up on Windows after we almost went out of business because of a data leak due to a .NET bug. Anyone still using doesn't care about security.
Which bug was that?
