Descriptions
An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
Una solución anterior para la vulnerabilidad de comunicación entre procesos (IPC), CVE-2011-3079, añadía una autenticación para comunicaciones entre endpoints de IPC y servidores padres durante la creación de procesos IPC. Dicha autenticación no es suficiente para canales creados después de que el proceso IPC se inicie, lo que conduce a su aplicación incorrecta a canales posteriores. Esto podría permitir un escape del sandbox a través de canales IPC debido a la falta de la validación de mensajes en el proceso en escucha. Esta vulnerabilidad afecta a las versiones anteriores a la 60.5 de Thunderbird, las versiones anteriores a la 60.5 de Firefox ESR y las versiones anteriores a la 65 de Firefox.
