<description>
<p>A vulnerability has been discovered in GLib. Please review the CVE identifier referenced below for details.</p>
</description>
<impact type="high">
<p>When a GDBus-based client subscribes to signals from a trusted system service such as NetworkManager or logind on a shared computer, other users of the same computer can send spoofed D-Bus signals that the GDBus-based client will wrongly interpret as having been sent by the trusted system service. This could lead to the GDBus-based client behaving incorrectly, with an application-dependent impact.</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All GLib users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/glib-2.78.6"
</code>
</resolution>
