-Fixes:
+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.
+ (CVE-2014-3639, fd.o #80919; Alban Crequy)
+
+Other fixes:
• Check for libsystemd from systemd >= 209, falling back to
the older separate libraries if not found (Umut Tezduyar Lindskog,
