Problem Description:

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.

Impact:

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.
