Improper XML Parsing in Zoom Client for Meetings

Description

The Zoom Client for Meetings (for Android, iOS, Linux, MacOS, and Windows) before version 5.10.0 failed to properly parse XML stanzas in XMPP messages. This can allow a malicious user to break out of the current XMPP message context and create a new message context to have the receiving users client perform a variety of actions.This issue could be used in a more sophisticated attack to forge XMPP messages from the server.
