Libcontainer and Docker Engine before 1.6.1 opens the file-descriptor passed to the pid-1 process before performing the chroot, which allows local users to gain privileges via a symlink attack in an image.

Security readout for executives and security teams

This is an old Docker container runtime flaw affecting Docker Engine/libcontainer before 1.6.1. A local user with control over a container image could use a symlink condition during container setup to gain elevated privileges. It matters mainly for legacy hosts still running very old Docker versions or accepting untrusted images. Exposure is most likely on legacy Linux systems running Docker Engine/libcontainer before 1.6.1, especially where local users, CI jobs, or tenants can provide or run container images. Prioritize remediation if any business system still runs Docker versions from before 1.6.1. The issue is old, but privilege escalation in container infrastructure can undermine host isolation and tenant boundaries. Mitigation focus: Upgrade Docker Engine/libcontainer to 1.6.1 or a vendor-supported fixed release.; Check distribution advisories for backported packages on SUSE/openSUSE and similar platforms.; Restrict who can build, import, or run container images on affected hosts..
