Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Zoom Opener installer is downloaded by a user from the Launch meeting page, when attempting to join a meeting without having the Zoom Meeting Client installed. The Zoom Opener installer for Zoom Client for Meetings before version 5.10.3 and Zoom Rooms for Conference Room for Windows before version 5.10.3 are susceptible to a DLL injection attack. This vulnerability could be used to run arbitrary code on the victims host.
