CWEhttps://cwe.mitre.org/data/definitions/706.html

runc through 1.0.0-rc9 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. (This vulnerability does not affect Docker due to an implementation detail that happens to block the attack.)

Weakness

The product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere.
