To me, these look like things that could be used for local escalation or MITM attacks. This is not good but frankly, for most of Zooms use cases, it's not an issue. The only frightening thing is the turbojpeg.dll one. A POC that leads to an RCE or even a crash would be devastating for Zoom, especially considering the amount of edu setups that don't enforce passwords even now.
IDK, for me and the edu organization I'm responsible for Zoom has been a great offering (especially considering the pricing they were able to offer by default for edu and after very little negotiation) but we are actively looking at teams as a successor for the next semester. Zoom has had 3 killer features over teams (virtual background, easy dial-in, no effort guests) and all of them have gone away now with the recent teams changes. If teams finally gets customer skype calling figured out Zoom will most likely be done in the edu field because that's quite a big part of switching to teams for an all out integrated comms solution, especially since you can't use your office 365 account for consumer skype.
