CVE-2019-9802

Priority
Description
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.
