Description Siddharth Sharma 2016-09-20 02:22:13 EDT

Due to flaws in the process we used to update "Preloaded Public Key Pinning" in our releases, the pinning for add-on updates became ineffective in early September. An attacker who was able to get a mis-issued certificate for a Mozilla web site could send malicious add-on updates to users on networks controlled by the attacker. Users who have not installed any add-ons are not affected.
