system bus by sending them a message containing a file descriptor,
then causing that file descriptor to exceed the kernel's maximum
recursion depth (itself introduced to fix a DoS) before dbus-daemon
forwards the message to the victim process. Most services and

denial of service.
Additionally, Alban discovered that bug fd.o#79694, a bug previously
reported by Alejandro Martinez Suarez which was n believed to be

causing dbus-daemon to attempt to forward invalid file descriptors to
a victim process when file descriptors become associated with the
