CVE-2015-2925: Path Traversal

First published: Fri Apr 03 2015(Updated: )

A flaw was found in the way the Linux kernel's file system implementation handled rename operations in which the source was inside and the destination was outside of a bind mount. A privileged user inside a container could use this flaw to escape the bind mount and, potentially, escalate their privileges on the system.
