@663e5b60 Interesting, just looked into this further in Microsoft's own guidance here: https://msrc.microsoft.com/blog/2023/10/microsofts-response-to-open-source-vulnerabilities-cve-2023-4863-and-cve-2023-5217/ It does indeed list Edge as the only product patched, maybe Microsoft uses their own VP codec for their video conferencing products & not the open source libvpx codec?
