It's reasonable to assume that reporter did not touch the "Backport:" field at all. The issue was reported for ruby 2.1.2p168 (see the "ruby -v" field). Backport value was original set to: 2.0.0: UNKNOWN, 2.1: UNKNOWN which happens to be the default value pre-filed into the field for you by the bug tracker when you try create a new issue. You can easily check by visiting: https://bugs.ruby-lang.org/projects/ruby-trunk/issues/new All changes from UNKNOWN to REQUIRED were not done by the reporter, as you can see from the bug comments. I don't think you can draw the conclusion based on the Backport field. -- Tomas Hoger / Red Hat Security Response Team
