On Linux systems, if the content process is compromised, the sandbox broker
will allow files to be truncated even though the sandbox explicitly only
has read access to the local file system and no write permissions. Note:
This attack only affects the Linux operating system. Other operating
systems are not affected. This vulnerability affects Firefox < 55.
