Zoom On-Premise Meeting Connector Zone Controller (ZC) before version 4.8.20220419.112 fails to properly parse STUN error codes, which can result in memory corruption and could allow a malicious actor to crash the application. In versions older than 4.8.12.20211115, this vulnerability could also be leveraged to execute arbitrary code.
