Description Kai Engert (:kaie) (inactive account) 2017-01-19 21:42:05 UTC
We will update RHEL 6.x to NSS 3.28, which is incompatible with Mozilla 50 and older versions, depending on which features are enabled in NSS RHEL.

Because we most like keep an older nss-softokn version in RHEL 6.x, this might be a non-issue.

However, I recommend that you pick up a small patch in Thunderbird, and other applications such as xulrunner (if we're using any such applications in RHEL), to prevent potentially issues.

The issue is not so much 3.28 as the X25519 that this version adds, and since the implementation of x25519 is in softokn, that is incompatibility with nss-softokn 3.28 package.
