After communication with MITRE, this CVE *might* overlap CVE-2018-1000656.
CVE-2019-1010083 was back then assigned by the DWF CNA, but the exact scope
of the CVE is unclear and might for instance be for an incomplete fix of
CVE-2018-1000656. As such it was only noted with a "may overlap". The
CVE-2019-1010083 only refers to the 1.0 release announcement and it is
guaranteed that it relates as well to pull request 2691. Upstream itself did
not comment on direct pings/questions back.
