dbus version control is now hosted on freedesktop.org's Gitlab
installation, and bug reports and feature requests have switched from
Bugzilla bugs (indicated by "fd.o #nnn") to Gitlab issues ("dbus#nnn")
and merge requests ("dbus!nnn").

• Prevent reading up to 3 bytes beyond the end of a truncated message.
  This could in principle be an information leak or denial of service
  on the system bus, but is not believed to be exploitable to crash
  the system bus or leak interesting information in practice.

• Stop the dbus-daemon leaking memory (an error message) if delivering
  the message that triggered auto-activation is forbidden. This is
  technically a denial of service because the dbus-daemon will
  run out of memory eventually, but it's a very slow and noisy one,
  because all the rejected messages are also very likely to have
  been logged to the system log, and its scope is typically limited by
  the finite number of activatable services available.

Fixes:

• Increase system dbus-daemon's RLIMIT_NOFILE rlimit before it drops
  privileges, because it won't have permission afterwards. This fixes a
  regression in dbus 1.10.18 and 1.11.0 which made the standard system bus
  more susceptible to deliberate or accidental denial of service.

Fixes:

• When parsing dbus-daemon configuration, tell Expat not to use
  cryptographic-quality entropy as a salt for its hash tables: we trust
  the configuration files, so we are not concerned about algorithmic
  complexity attacks via hash table collisions. This prevents
  dbus-daemon --system from holding up the boot process (and causing
  early-boot system services like systemd, logind, networkd to time
  out) on entropy-starved embedded systems.

• Prevent symlink attacks in the nonce-tcp transport on Unix that could
  allow an attacker to overwrite a file named "nonce", in a directory
  that the user running dbus-daemon can write, with a random value
  known only to the user running dbus-daemon. This is unlikely to be
  exploitable in practice, particularly since the nonce-tcp transport
  is really only useful on Windows.

  On Unix systems we strongly recommend using only the unix: and systemd:
  transports, together with EXTERNAL authentication. These are the only

• Work around an undesired effect of the fix for CVE-2014-3637
  (fd.o #80559), in which processes that frequently send fds, such as
  logind during a flood of new PAM sessions, can get disconnected for
  continuously having at least one fd "in flight" for too long;
  dbus-daemon interprets that as a potential denial of service attack.
  The workaround is to disable that check for uid 0 process such as
  logind, with a message in the system log. The bug remains open while
  we look for a more general solution.

The “not excessively inhospitable” release.

Security fixes:

• Do not treat ActivationFailure message received from root-owned systemd
  name as a format string. In principle this is a security vulnerability,
  but we do not believe it is exploitable in practice, because only
  privileged processes can own the org.freedesktop.systemd1 bus name, and
  systemd does not appear to send activation failures that contain "%".

  Please note that this probably *was* exploitable in dbus versions
  older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
  the time was only thought to be a denial of service vulnerability
  (CVE-2015-0245). If you are still running one of those versions,
  patch or upgrade immediately.

  (fd.o #98157, Simon McVittie)

Other fixes:

• Harden dbus-daemon against malicious or incorrect ActivationFailure
  messages by rejecting them if they do not come from a privileged
  process, or if systemd activation is not enabled

The “0x20” release.

This is a new stable branch, recommended for use in OS distributions.

Fixes since 1.9.20:

• distribute test/tap-test.sh.in, even if the tarball was built without
  tests enabled (fd.o #91684, Simon McVittie)
• work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)

Summary of major changes since 1.8.0:

• The basic setup for the well-known system and session buses is
  now done in read-only files in ${datadir} (normally /usr/share).
  See the NEWS entry for 1.9.18 for details.

• AppArmor integration has been merged, with features similar to the
  pre-existing SELinux integration. It is mostly compatible with the
  patches previously shipped by Ubuntu, with one significant change:
  Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
  by GetConnectionCredentials and was not included.

• The --enable-user-session configure option can be enabled
  by OS integrators intending to use systemd to provide a session bus
  per user (in effect, treating all concurrent graphical and non-graphical
  login sessions as one large session).

• The new listenable address mode "unix:runtime=yes" listens on
  $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
  user session. libdbus and "dbus-launch --autolaunch" will connect to
  this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
  matching default.

• All executables are now dynamically linked to libdbus-1.
  Previously, some executables, most notably dbus-daemon, were statically
  linked to a specially-compiled variant of libdbus. This results in
  various private functions in the _dbus namespace being exposed by the
  shared library. These are not API, and must not be used outside
  the dbus source tree.

• On platforms with ELF symbol versioning, all public symbols
  are versioned LIBDBUS_1_3.

New bus APIs:

• org.freedesktop.DBus.GetConnectionCredentials returns
  LinuxSecurityLabel where supported
• org.freedesktop.DBus.Monitoring interface (privileged)
  · BecomeMonitor method supersedes match rules with eavesdrop=true,
    which are now deprecated
• org.freedesktop.DBus.Stats interface (semi-privileged)
  · now enabled by default
  · new GetAllMatchRules method
464 465
• org.freedesktop.DBus.Verbose interface (not normally compiled)
  · toggles the effect of DBUS_VERBOSE
466 467 468 469 470 471 472 473 474 475 476 477 478 479 480 481 482 483 484 485 486 487 488 489 490

New executables:

• dbus-test-tool
• dbus-update-activation-environment

New optional dependencies:

• The systemd: pseudo-transport requires libsystemd or libsd-daemon
• Complete documentation requires Ducktype and yelp-tools
• Full test coverage requires GLib 2.36 and PyGI
• AppArmor integration requires libapparmor and optionally libaudit

Dependencies removed:

• dbus-glib

The “Remember Tomorrow” release.

This is a release-candidate for D-Bus 1.10.0. OS distribution vendors

Configuration changes:

• The basic setup for the well-known system and session buses is now done
  in read-only files in ${datadir}, moving a step closer to systems
  that can operate with an empty /etc directory. In increasing order
  of precedence:

  · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
    the default message policies.
  · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
    dbus still installs a trivial version of each, for documentation
    purposes; putting configuration directives in these files is deprecated.
  · ${datadir}/dbus-1/s*.d/ are now available for third-party software
    to install "drop-in" configuration snippets (any packages
    using those directories should explicitly depend on at least this
    version of dbus).
  · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
    or third-party software to install "drop-in" configuration snippets
  · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
    overrides

  ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
  and "s*" refers to either system or session as appropriate.

561 562 563 564 565 566 567 568 569

  If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
  in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
  NFS or similar, you will need to reconfigure the session bus to accept
  DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
  is not recommended.

• Do not allow non-uid-0 processes to send forged ActivationFailure
  messages. On Linux systems with systemd activation, this would
  allow a local denial of service: unprivileged processes could
  flood the bus with these forged messages, winning the race with
  the actual service activation and causing an error reply
  to be sent back when service auto-activation was requested.

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)

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.

• 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>
  </busconfig>

  (fd.o #86431, Simon McVittie)

• Add a message in syslog/the Journal when the auth_timeout is exceeded

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.

  denial of service.

  message in quick succession contains fds. This prevents another attack

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

  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.

The “extreme hills” release.

Dependencies:

• If systemd support is enabled, libsystemd-journal is now required.

Enhancements:

• When activating a non-systemd service under systemd, annotate its
  stdout/stderr with its bus name in the Journal. Known limitation:
  because the socket is opened before forking, the process will still be
  logged as if it had dbus-daemon's process ID and user ID.

Build-time configuration changes:

• The --with-dbus-session-bus-default-address configure option is no longer
  supported. Use the new --with-dbus-session-bus-connect-address and
  --with-dbus-session-bus-listen-address options instead. On Windows, you
  usually want them to have the same argument; on Unix, the defaults are
  usually correct.

• Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer

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)

Changes since 1.5.12:
