<background>
|
|
<p>D-Bus is a message bus system, a simple way for applications to talk to
|
|
one another.

|
|
<description>
|
|
<p>It was discovered that D-Bus incorrectly handles certain format strings.</p>
|
|
|
|
<p>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 type="normal">
|
|
<p>A local attacker could cause a Denial of Service condition or possibly
|
|
execute arbitrary code.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>The vulnerable D-Bus interface is intended only for use by systemd
|
|
running as root.
|
|
</p>
|
|
|
|
<p>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.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All D-Bus users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-apps/dbus-1.10.12"
|
|
</code>
|
|
</resolution>
