This is primarily done out of an abudance of caution against runc exec being attacked by a container where /dev/pts/ptmx has been replaced with some other bad inode (a disconnected NFS handle, a symlink that goes through a leaked runc file descriptor to reference a host ptmx, etc). Unfortunately, we cannot trivially verify that /dev/pts/ptmx is actually the /dev/pts from the container without storing stuff like the fsid in the runc state.json, which is probably not worth the extra effort. This should at least avoid the most concerning cases. Reported-by: Aleksa Sarai <cyphar@cyphar.com> Signed-off-by: Aleksa Sarai <cyphar@cyphar.com>
