How? It doesn't apply to any release. It's CVE who should fix their 
description.

Also, i consider it a bit premature to make a CVE for an issue that's 
only present in git master and was fixed immediately after it was 
reported to us. It wasn't realistically deployed anywhere and only pads 
the list.
