Only the docker image with the latest version of R is supported with security updates.
To report a vulnerability in the latest docker image, email the maintainer olivier.benz@b-data.ch.
Vulnerabilities in docker images with prior versions of R are not fixed.
Whenever a new version of R is released, the previous version's docker image is rebuilt once again and then frozen.
Docker images may be rebuilt or extended if they fail to start or have runtime issues.
