Thank you.

DMO stands for DirectX media objects. These are the codecs and video
filters used in DirectShow. So, potentially, all the applications
using external codecs or filters are vulnerable. And the issue with
wintab32.dll is caused by Qt, so developers using Qt should check
their applications.
