That is, couldn't someone gain elevated permissions within the changed root, and then exploit his access to /dev via that bound mount to escape the chroot/scribble on devices/whatever? The point of a chroot is that it NOT have access to the outside system... and if it must have access to device nodes, they should be device nodes donated strictly to the chroot. -- gabriel rosenkoetter gr@eclipsed.net Attachment:
