Description Adam Mariš 2016-03-09 13:29:26 UTC

It was reported that by creating a new image with root password changed and using it as a sti builder image, attackers are able to gain ROOT in it. Overridding builder image scripts(e.g. assemble) can help the attackers to access the pod and/or perform remote command execution in it.
