The following flaw has been fixed in Docker 1.3.2:
Docker versions 1.3.0 through 1.3.1 allowed security options to be applied
to images, allowing images to modify the default run profile of containers
executing these images. This vulnerability could allow a malicious image
creator to loosen the restrictions applied to a container’s processes,
potentially facilitating a break-out.
Docker 1.3.2 remedies this vulnerability. Security options applied to
images are no longer consumed by the Docker engine and will be ignored.
Users are advised to upgrade.
Red Hat would like to thank the Docker project for reporting this issue.
Created docker-io tracking bugs for this issue:
Affects: fedora-all [bug 1167507]
Affects: epel-6 [bug 1167508]
This issue did not affect the version of Docker as shipped with Red Hat Enterprise Linux 7.
The next current release of Docker is < 1.30 and the next release will be based off of 1.3.2 or greater.
docker-io-1.3.2-2.fc21 has been pushed to the Fedora 21 stable repository. If problems still persist, please make note of it in this bug report.
