      Are embargoes on (open source) security bugs needed? Only in the most extreme cases, @kurtseifried argueshttps://securityblog.redhat.com/2015/06/10/the-hidden-costs-of-embargoes/ …

      @dakami @virusbtn I'd argue most vulns don't matter warrant embargo, eg /tmp file vulns, you really think we need to embargo those?

          @dakami @taviso @virusbtn more to the point though: why keep bugs secret that no attacker cares about?
