Descriptions

A vulnerability in the way Cisco Webex applications process Universal Communications Format (UCF) files could allow an attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient validation of UCF media files. An attacker could exploit this vulnerability by sending a user a malicious UCF file through a link or email attachment and persuading the user to open the file with the affected software on the local system. A successful exploit would cause the application to quit unexpectedly.

Una vulnerabilidad en la manera en que las aplicaciones de Cisco Webex procesan los archivos de Universal Communications Format (UCF) podría permitir a un atacante causar una condición de denegación de servicio (DoS). La vulnerabilidad es debido a una comprobación insuficiente de los archivos multimedia UCF. Un atacante podría explotar esta vulnerabilidad mediante el envío a un usuario de un archivo UCF malicioso mediante un enlace o archivo adjunto de correo electrónico y persuadiendo al usuario a abrir el archivo con el software afectado en el sistema local. Una explotación con éxito podría causar que la aplicación se cierre inesperadamente
