Red Hat Bugzilla is not an appropriate forum for reporting security bugs in upstream components. As you can see, your bug report here has been ignored for three years, and will likely continue to be ignored, so I'm going to go ahead and close it. Please feel free to report this upstream if you want the developers to look at it.
