dbus is vulnerable to authentication bypass. A mishandling of the reference implementation of the DBUS_COOKIE_SHA allows an attacker with write access to its own home directory to spoof the cookie by manipulating a ~/.dbus-keyrings symlink which causes the DBusServer with a different uid to read and write in unintended locations.
