openSUSE Security Update : dbus-1 / dbus-1-x11 (openSUSE-2015-150)

This script is Copyright (C) 2015 Tenable Network Security, Inc.


Synopsis :

The remote openSUSE host is missing a security update.

Description :

dbus-1, dbus-1-x11 were updated to version 1.8.16 to fix one security
issue.

This update fixes the following security issue :

- CVE-2015-0245: 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 (bnc#916343).

These additional security hardenings are included :

- 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.

- 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.
