I'll let docker's security team know that an insecure, obsolete docker image is being served and the maintainers have officially acknowledged they will no longer support it. Best to get insecure and vulnerable software out of the hands of those who may not be familiar with this CVE or their change in policy that has not gotten a press release in any way.
Actually, Docker did something like that, where they limited the amount of docker images they would host for you for free to a reasonable number. The result was pretty similar to this current outcry: https://news.ycombinator.com/item?id=24143588
