Descriptions

Insufficient vetting of parameters passed with the Prompt:Open IPC message between child and parent processes can result in the non-sandboxed parent process opening web content chosen by a compromised child process. When combined with additional vulnerabilities this could result in executing arbitrary code on the user's computer. This vulnerability affects Firefox ESR < 60.7.2, Firefox < 67.0.4, and Thunderbird < 60.7.2.

Una revisión insuficiente de los parámetros pasados ??con el mensaje IPC de Prompt:Open, entre procesos hijo y padre puede resultar que el proceso padre fuera del Sandbox abra el contenido web elegido por un proceso hijo comprometido. Cuando se combina con vulnerabilidades adicionales, esto podría resultar en la ejecución de código arbitrario en el ordenador del usuario. Esta vulnerabilidad afecta a Firefox ESR anterior a versión 60.7.2, Firefox anterior a versión 67.0.4 y Thunderbird anterior a versión 60.7.2.

Mozilla Firefox and Thunderbird contain a sandbox escape vulnerability that could result in remote code execution.
