+ <h1>Problem Description:</h1>
+ <p>When a process, such as jexec(8) or killall(1), calls jail_attach(2)
+ to enter a jail, the jailed root can attach to it using ptrace(2) before
+ the current working directory is changed.</p>
+ <h1>Impact:</h1>
+ <p>A process with superuser privileges running inside a jail could change
+ the root directory outside of the jail, thereby gaining full read and
+ writing access to all files and directories in the system.</p>
