Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird
< 45.4 rely on unintended expiration dates for Preloaded Public Key
Pinning, which allows man-in-the-middle attackers to spoof add-on updates
by leveraging possession of an X.509 server certificate for
addons.mozilla.org signed by an arbitrary built-in Certification Authority.
