CVE-2021-30465: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
(updated )
runc before 1.0.0-rc95 allows a Container Filesystem Breakout via Directory Traversal. To exploit the vulnerability, an attacker must be able to create multiple containers with a fairly specific mount configuration. The problem occurs via a symlink-exchange attack that relies on a race condition.
