Descriptions

Stack-based buffer overflow in the ZoomLauncher binary in the Zoom client for Linux before 2.0.115900.1201 allows remote attackers to execute arbitrary code by leveraging the zoommtg:// scheme handler.

Desbordamiento de búfer basado en pila en el binario ZoomLauncher del cliente Zoom para Linux en versiones anteriores a la 2.0.115900.1201 permite que atacantes remotos ejecuten código arbitrario aprovechando el controlador de esquemas zoommtg://.

The binary /opt/zoom/ZoomLauncher is vulnerable to a buffer overflow because it concatenates a overly long user input to a stack variable without checking if the destination buffer is long enough to hold the data. The binary also has important security features like canary turned off. The client registers a scheme handler (zoommtg://) and this makes possible to trigger the vulnerability remotely. Version 2.0.106600.0904 is affected.
