dbus 1.14.6 (2023-02-08)
	Denial of service fixes:
	• Fix an incorrect assertion that could be used to crash dbus-daemon or
	  other users of DBusServer prior to authentication, if libdbus was compiled
	  with assertions enabled.
	  We recommend that production builds of dbus, for example in OS distributions,
	  should be compiled with checks but without assertions.
	  (dbus#421, Ralf Habacker; thanks to Evgeny Vereshchagin)
	Other fixes:
	• When connected to a dbus-broker, stop dbus-monitor from incorrectly
	  replying to Peer method calls that were sent to the dbus-broker with
	  a NULL destination (dbus#301, Kai A. Hiller)
	• Fix out-of-bounds varargs read in the dbus-daemon's config-parser.
	  This is not attacker-triggerable and appears to be harmless in practice,
	  but is technically undefined behaviour and is detected as such by
	  AddressSanitizer. (dbus!357, Evgeny Vereshchagin)
	• Avoid a data race in multi-threaded use of DBusCounter
	  (dbus#426, Ralf Habacker)
	• Fix a crash with some glibc versions when non-auditable SELinux events
	  are logged (dbus!386, Jeremi Piotrowski)
	• If dbus_message_demarshal() runs out of memory while validating a message,
	  report it as NoMemory rather than InvalidArgs (dbus#420, Simon McVittie)
	• Use C11 _Alignof if available, for better standards-compliance
	  (dbus!389, Khem Raj)
	• Stop including an outdated copy of pkg.m4 in the git tree
	  (dbus!365, Simon McVittie)
	• Documentation:
	  · Consistently use Gitlab bug reporting URL (dbus!372, Marco Trevisan)
	• Tests fixes:
	  · Fix the test-apparmor-activation test after dbus#416
	    (dbus!380, Dave Jones)
	Internal changes:
	• Fix CI builds with recent git versions (dbus#447, Simon McVittie)
