Title: D-Bus: Format string vulnerability
Date: January 11, 2017
Bugs: #596772
ID: 201701-20

Synopsis
========
A vulnerability has been found in D-Bus possibly resulting in a local
Denial of Service.
Background
==========
D-Bus is a message bus system, a simple way for applications to talk to
one another.
Affected packages
=================
——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 sys-apps/dbus < 1.10.12 >= 1.10.12
Description
===========
It was discovered that D-Bus incorrectly handles certain format
strings.
The impact of this new vulnerability is believed to not be exploitable
if D-Bus is patched against CVE-2015-0245. The previous vulnerability
(CVE-2015-0245) was addressed in GLSA-201503-02 referenced below.
Impact
======
A local attacker could cause a Denial of Service condition or possibly
execute arbitrary code.
Workaround
==========
The vulnerable D-Bus interface is intended only for use by systemd
running as root.
The administrator can install a policy which denies sending from
org.freedesktop.systemd1.Activator” to D-Bus. This will prevent
non-root attackers from reaching the interface in order to exercise
this flaw.
Resolution
==========
All D-Bus users should upgrade to the latest version:
# emerge –sync
# emerge –ask –oneshot –verbose “>=sys-apps/dbus-1.10.12”
