<background>
<p>polkit is a toolkit for managing policies relating to unprivileged
processes communicating with privileged processes.
</p>
</background>
<description>
<p>polkit has a race condition which potentially allows a process to change
its UID/EUID via suid or pkexec before authentication is completed.
</p>
</description>
<impact type="high">
<p>A local attacker could start a suid or pkexec process through a
polkit-enabled application, which could result in privilege escalation or
bypass of polkit restrictions.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All polkit users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-auth/polkit-0.112"
</code>
<p>All HPLIP users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-print/hplip-3.14.1"
</code>
<p>All Spice-Gtk users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/spice-gtk-0.21"
</code>
<p>All systemd users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/systemd-204-r1"
</code>
<p>All libvirt users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-emulation/libvirt-1.1.2-r3"
