  • Win10 codec security hole

    Posted on June 30, 2020 at 17:18 CDT by • Comment in the Forums

    This one’s more interesting than the typical Windows zero-day.

    MS just published a Security Update for CVE-2020-1425 | Microsoft Windows Codecs Library Remote Code Execution Vulnerability:

    A remoted code execution vulnerability exists in the way that Microsoft Windows Codecs Library handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system. Exploitation of the vulnerability requires that a program process a specially crafted image file. The update addresses the vulnerability by correcting how Microsoft Windows Codecs Library handles objects in memory.

    (It looks like the bad codec is a piece of Windows that decompresses a video file.)

    It’s listed as not exploited, not yet disclosed. So it’s a real security hole, but it hasn’t been exploited yet – so it isn’t a zero-day.

    Affected customers will be automatically updated by Microsoft Store. Customers do not need to take any action to receive the update. Alternatively, customers who want to receive the update immediately can check for updates with the Microsoft Store App; more information on this process can be found here.

    Nothing to see here, folks.
