CVE-2021-34408

The Zoom Client for Meetings for Windows in all versions before version 5.3.2 writes log files to a user writable directory as a privileged user during the installation or update of the client. This could allow for potential privilege escalation if a link was created between the user writable directory used and a non-user writable directory.
