<p>It was found that systemd incorrectly handled certain Polkit queries.</p>
</description>
<impact type="high">
<p>A local unprivileged user, by sending a specially crafted Polkit query,
could possibly execute arbitrary code with the privileges of the process,
escalate privileges or cause a Denial of Service condition.

</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All systemd users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/systemd-244.3"
</code>
</resolution>
