Announcing dbus 1.10.32 security update

[Simon McVittie]

dbus is the reference implementation of D-Bus, a message bus for
communication between applications and system services.

The dbus 1.10.x branch was originally released in 2015. It currently
receives security-fix releases whenever necessary, but it is planned to
reach end-of-life status at the end of Debian 9's official security
support (approximately July 2020). If you are a dbus downstream
maintainer in a long-lived OS distribution and you want to use the
upstream dbus-1.10 git branch as a place to share backported security
fixes with other distributions, please contact the dbus maintainers via
the dbus-security mailing list on lists.freedesktop.org.

The “technically a venom” release.

Maybe security fixes:

• 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.

Other fixes:

• On Solaris and its derivatives, if a cmsg header is truncated, ensure
  that we do not overrun the buffer used for fd-passing, even if the
  kernel tells us to.
