Description

New security release. "Upgrading is recommended".


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

This is a stable-branch release, including a fix that addresses
a security vulnerability (on systems that are arguably misconfigured).
Upgrading is recommended.

<http://dbus.freedesktop.org/releases/dbus/dbus-1.12.20.tar.gz>
<http://dbus.freedesktop.org/releases/dbus/dbus-1.12.20.tar.gz.asc>
git tag: dbus-1.12.20

The “temporary nemesis” 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.
  (dbus#305, dbus!166; Simon McVittie)

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.

We're waiting on changes by Thomas in BLFS (he's gone until Sunday Evening) for elogind systems. I don't feel comfortable doing this update until after he returns.

I'll get this done Sunday night.

As LFS doesn't use users with same UID I think we can wait. (Is there anyone really using this stupid "feature"?)

comment:2 by Pierre Labastie, 4 years ago

Since changes are needed for BLFS ticket #13748, I guess it'll be updated there too, so for keeping lfs in sync, I'd suggest updating it (when Thomas is back).
