* 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.
* 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
* 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.
* Avoid a data race in multi-threaded use of DBusCounter
* 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
* Stop including an outdated copy of pkg.m4 in the git tree
* Documentation:
* Fix the test-apparmor-activation test after dbus#416
* Internal changes:
* Fix CI builds with recent git versions (dbus#447, Simon
McVittie)
- switch to using multibuild

* On Unix, avoid a use-after-free if two usernames have the same
numeric uid. In older versions this could lead to a crash (denial of
service) or other undefined behaviour, possibly including incorrect
authorization decisions if <policy group=...> is used.
Like Unix filesystems, D-Bus' model of identity cannot distinguish
between users of different names with the same numeric uid, so this
configuration is not advisable on systems where D-Bus will be used.
Thanks to Daniel Onaca.

- From 1.12.18
* CVE-2020-12049: If a message contains more file descriptors than can
be sent, close those that did get through before reporting error.
Previously, a local attacker could cause the system dbus-daemon (or
another system service with its own DBusServer) to run out of file
descriptors, by repeatedly connecting to the server and sending fds that
would get leaked.
Thanks to Kevin Backhouse of GitHub Security Lab.
(dbus#294, GHSL-2020-057; Simon McVittie)
* Fix a crash when the dbus-daemon is terminated while one or more
monitors are active (dbus#291, dbus!140; Simon McVittie)
* The dbus-send(1) man page now documents --bus and --peer instead of
the old --address synonym for --peer, which has been deprecated since
the introduction of --bus and --peer in 1.7.6
(fd.o #48816, dbus!115; Chris Morin)
* Fix a wrong environment variable name in dbus-daemon(1)
(dbus#275, dbus!122; Mubin, Philip Withnall)
* Fix formatting of dbus_message_append_args example
(dbus!126, Felipe Franciosi)
* Avoid a test failure on Linux when built in a container as uid 0, but
