+ <h1>Problem Description:</h1>
+ <p>Due to a race condition between lookup of ".." and remounting a filesystem,
+ a process running inside a jail might access filesystem hierarchy outside
+ of jail.</p>
+ <h1>Impact:</h1>
+ <p>A process with superuser privileges running inside a jail configured
+ with the allow.mount permission (not enabled by default) could change the root
+ directory outside of the jail, and thus gain full read and write access
+ to all files and directories in the system.</p>
