NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

Mozilla Firefox before 39.0, Firefox ESR 38.x before 38.1, and Thunderbird before 38.1 do not enforce key pinning upon encountering an X.509 certificate problem that generates a user dialog, which allows user-assisted man-in-the-middle attackers to bypass intended access restrictions by triggering a (1) expired certificate or (2) mismatched hostname for a domain with pinning enabled.
