Enhancements:

• The new Monitoring interface in the dbus-daemon lets dbus-monitor and
  similar tools receive messages without altering the security properties
  of the system bus, by calling the new BecomeMonitor method on a
  private connection. This bypasses the normal <allow> and <deny> rules
  entirely, so to preserve normal message-privacy assumptions, only root
  is allowed to do this on the system bus. Restricted environments,
  such as Linux with LSMs, should lock down access to the Monitoring
  interface. (fd.o #46787, Simon McVittie)

• dbus-monitor uses BecomeMonitor to capture more traffic, if the
  dbus-daemon supports it and access permissions allow it.
  It still supports the previous approach ("eavesdropping" match rules)
  for compatibility with older bus daemons. (fd.o #46787, Simon)

• dbus-monitor can now log the message stream as binary data for later
  analysis, with either no extra framing beyond the normal D-Bus headers,
  or libpcap-compatible framing treating each D-Bus message
  as a captured packet. (fd.o #46787, Simon)

Fixes:

• Fix some CMake build regressions (fd.o #88964, Ralf Habacker)

• On Unix, forcibly terminate regression tests after 60 seconds to
  prevent them from blocking continuous integration frameworks
  (fd.o #46787, Simon)

Security hardening:

• Do not allow calls to UpdateActivationEnvironment from uids other than
  the uid of the dbus-daemon. If a system service installs unsafe
  security policy rules that allow arbitrary method calls
  (such as CVE-2014-8148) then this prevents memory consumption and
  possible privilege escalation via UpdateActivationEnvironment.

  We believe that in practice, privilege escalation here is avoided
  by dbus-daemon-launch-helper sanitizing its environment; but
  it seems better to be safe.

• Do not allow calls to UpdateActivationEnvironment or the Stats interface
  on object paths other than /org/freedesktop/DBus. Some system services
  install unsafe security policy rules that allow arbitrary method calls
  to any destination, method and interface with a specified object path;
  while less bad than allowing arbitrary method calls, these security
  policies are still harmful, since dbus-daemon normally offers the
  same API on all object paths and other system services might behave
  similarly.

Other fixes:

• Add missing initialization so GetExtendedTcpTable doesn't crash on
  Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)

• Partially revert the CVE-2014-3639 patch by increasing the default
  authentication timeout on the system bus from 5 seconds back to 30
  seconds, since this has been reported to cause boot regressions for
  some users, mostly with parallel boot (systemd) on slower hardware.

  On fast systems where local users are considered particularly hostile,
  administrators can return to the 5 second timeout (or any other value
  in milliseconds) by saving this as /etc/dbus-1/system-local.conf:

  <busconfig>
    <limit name="auth_timeout">5000</limit>

The "smashy smashy egg man" release.

Security fixes:

• Do not accept an extra fd in the padding of a cmsg message, which
  could lead to a 4-byte heap buffer overrun.
  (CVE-2014-3635, fd.o #83622; Simon McVittie)

• Reduce default for maximum Unix file descriptors passed per message
  from 1024 to 16, preventing a uid with the default maximum number of
  connections from exhausting the system bus' file descriptors under
  Linux's default rlimit. Distributors or system administrators with a
  more restrictive fd limit may wish to reduce these limits further.

  Additionally, on Linux this prevents a second denial of service
  in which the dbus-daemon can be made to exceed the maximum number
  of fds per sendmsg() and disconnect the process that would have
  received them.
  (CVE-2014-3636, fd.o #82820; Alban Crequy)

• Disconnect connections that still have a fd pending unmarshalling after
  a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
  removing the possibility of creating an abusive connection that cannot be
  disconnected by setting up a circular reference to a connection's
  file descriptor.
  (CVE-2014-3637, fd.o #80559; Alban Crequy)

• Reduce default for maximum pending replies per connection from 8192 to 128,
  mitigating an algorithmic complexity denial-of-service attack
  (CVE-2014-3638, fd.o #81053; Alban Crequy)

• Reduce default for authentication timeout on the system bus from
  30 seconds to 5 seconds, avoiding denial of service by using up
  all unauthenticated connection slots; and when all unauthenticated
  connection slots are used up, make new connection attempts block
  instead of disconnecting them.

The “Wolverine distrusts my printer” release.

This starts a new stable branch. The 1.6.x branch is now considered to be
outdated, and will only receive fixes for serious bugs such as security
flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
are unlikely to get any more releases, but if distributors still need to
support them, please share security patches via upstream.

Summary of changes since 1.6.x:

• libdbus always behaves as if dbus_threads_init_default() had been called
  (thread-safety by default)
• new dbus-run-session tool, replacing certain misuses of dbus-launch
• dbus-monitor can talk to outdated versions of dbus-daemon again
• new org.freedesktop.DBus.GetConnectionCredentials method
• GetConnectionUnixProcessID also works correctly on Windows, returning
  the Windows process ID
• GetConnectionWindowsSID returns the correct SID on Windows
• expat is required, libxml2 can no longer be used as a substitute
• the userDB cache is required, and cannot be disabled
• a 64-bit integer type (either int, long, long long or _int64) is required
• better systemd-journald integration on Linux
• fixed long-standing fd and array leaks when failing to parse a message
• fixed referenced-but-never-freed parent nodes (effectively memory leaks)
  when using certain object-path allocation patterns, notably in Avahi
• better defaults for Windows support
• better CMake support
• better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
• the source language for the man pages is now Docbook XML

• If the tests crash with an assertion failure, they no longer default to
  blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
  environment if you want the old behaviour.

• To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
  can be run with an external dbus-daemon by setting
  DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
  an unusually-configured dbus-daemon are skipped.

Dependencies:

• The Windows version of libdbus now contains a C++ source file, used
  to provide global initialization when the library is loaded.
  gcc (mingw*) users should ensure that g++ is also installed.

The “soul of this machine has improved” release.

This version starts a new stable branch of D-Bus: only bug fixes will
be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.

Summary of changes since 1.4.x:

• New requirements
  · PTHREAD_MUTEX_RECURSIVE on Unix
  · compiler support for 64-bit integers (int64_t or equivalent)

• D-Bus Specification v0.19

• New dbus-daemon features
  · <allow own_prefix="com.example.Service"/> rules allow the service to
    own names like com.example.Service.Instance3
  · optional systemd integration when checking at_console policies
  · --nopidfile option, mainly for use by systemd
  · path_namespace and arg0namespace may appear in match rules
  · eavesdropping is disabled unless the match rule contains eavesdrop=true

• New public API
  · functions to validate various string types (dbus_validate_path() etc.)
  · dbus_type_is_valid()
  · DBusBasicValue, a union of every basic type

• Bug fixes
  · removed an unsafe reimplementation of recursive mutexes
  · dbus-daemon no longer busy-loops if it has far too many file descriptors
  · dbus-daemon.exe --print-address works on Windows
  · all the other bug fixes from 1.4.20

• Other major implementation changes
  · on Linux, dbus-daemon uses epoll if supported, for better scalability
  · dbus_threads_init() ignores its argument and behaves like
    dbus_threads_init_default() instead
  · removed the per-connection link cache, improving dbus-daemon performance

• Developer features
  · optional Valgrind instrumentation (--with-valgrind)
  · optional Stats interface on the dbus-daemon (--enable-stats)
  · optionally abort whenever malloc() fails (--enable-embedded-tests
    and export DBUS_MALLOC_CANNOT_FAIL=1)

Notes for distributors:

  This version of D-Bus no longer uses -fPIE by default. Distributions wishing
  to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
  toolchain supports it reliably, via something like:

    ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"

  or by using distribution-specific wrappers such as Debian's hardening-wrapper.
