In the meantime, while I was on vacation, the above has been (accidentally) pushed as a stable update for Fedora 21 already: ca-certificates-2014.2.1-1.5.fc21.noarch It seems it will be included in the final release of Fedora 21. Given that we keep legacy trust enabled, and given that I haven't seen any problem reports, it's probably OK. Using the new ca-legacy utility, users/administrators who are willing to accept the compatibility issues and who prefer to closely follow the Mozilla CA trust decisions, can disable trust for the legacy root CA certificates as a systemwide configuration, by executing this command as root: ca-legacy disable The configuration will be remembered in /etc/pki/ca-trust/ca-legacy.conf and will be used on future package upgrades, when additional certificates are moved to the legacy state. If required, it's possible to undo the configuration and restore to the current default, using: ca-legacy enable The current configuration can be shown using: ca-legacy check Regarding Fedora 19 and Fedora 20: On F19/F20, GnuTLS is also affected by the breakage, when disabling trust for the legacy CAs, because GnuTLS has been enhanced in Fedora 21 and later, only. Updated packages for F19 and F20, that provide the update to version 2.1 of the ca-certificates list, and which also include the new ca-legacy utility and configuration mechanism, have been pushed to updates-testing: https://admin.fedoraproject.org/updates/ca-certificates-2014.2.1-1.5.fc19 https://admin.fedoraproject.org/updates/ca-certificates-2014.2.1-1.5.fc20 Kai -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
