the same-origin policy and inject web script into a non-privileged
part of the built-in PDF file viewer (PDF.js). An attacker could
create a malicious web page that, when viewed by a victim, could steal
arbitrary files (including private SSH keys, the /etc/passwd file, and
other potentially sensitive files) from the system running Firefox.
(CVE-2015-4495)

After installing the update, Firefox must be restarted for the changes
to take effect.");
