Severity ?
7.5 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
If a Sandbox content process is compromised, it can initiate an FTP download which will then use a child process to render the downloaded data. The downloaded data can then be passed to the Chrome process with an arbitrary file length supplied by an attacker, bypassing sandbox protections and allow for a potential memory read of adjacent data from the privileged Chrome process, which may include sensitive data. This vulnerability affects Firefox < 66.

Los datos descargados pueden ser pasados al proceso de Chrome con una longitud de archivo arbitraria proporcionada por un atacante, omitiendo las protecciones de la sandbox y permitiendo una lectura de memoria potencial de datos adyacentes del proceso de Chrome privilegiado, que puede incluir datos confidenciales. Esta vulnerabilidad afecta a Firefox versi\u00f3n anterior a la 66."
