dbus-broker: dbus-broker: session bus denial of service via EMFILE during peer setup

A flaw was found in dbus-broker. When the process file-descriptor limit is reached, EMFILE/ENFILE errors during peer setup notably SOPEERPIDFD are handled as fatal failures, causing the broker to exit. A local attacker who can open many connections to the user session bus can trigger this and den...
