Descriptions

The Zoom Client for Meetings for MacOS (Standard and for IT Admin) prior to version 5.9.6 failed to properly check the package version during the update process. This could lead to a malicious actor updating an unsuspecting user’s currently installed version to a less secure version.

Zoom Client for Meetings para MacOS (estándar y para administradores de TI) versiones anteriores a 5.9.6, no comprobaba apropiadamente la versión del paquete durante el proceso de actualización. Esto podría conllevar que un actor malicioso actualizara la versión actualmente instalada de un usuario desprevenido a una versión menos segura
