Video messaging giant Zoom has released patches for multiple security vulnerabilities that expose both Windows and macOS users to malicious hacker attacks.

The vulnerabilities, in the enterprise-facing Zoom Rooms product, could be exploited in privilege escalation attacks on both Windows and macOS platforms.

The company’s first batch of patches for 2023 includes patches for a trio of “high-severity” vulnerabilities in Zoom Room for Windows Installers, Zoom Room for Windows Clients and Zoom Rooms for macOS Clients.

Here’s how Zoom is documenting the high-risk issues:

Zoom also released fixes for a pair of medium-severity bugs in Zoom Rooms for macOS clients before version 5.11.4, warning that this version of the software contains an insecure key generation mechanism. 

“The encryption key used for IPC between the Zoom Rooms daemon service and the Zoom Rooms client was generated using parameters that could be obtained by a local low-privileged application. That key can then be used to interact with the daemon service to execute privileged functions and cause a local denial of service,” according to Zoom’s documentation.

Zoom also fixed a path traversal vulnerability in Zoom for Android Clients, warning that a third party app could exploit this vulnerability to read and write to the Zoom application data directory.
