        <p>uptimed is a system uptime record daemon that keeps track of your highest uptimes.</p>
    </background>
    <description>
        <p>Via unnecessary file ownership modifications in the pkg_postinst ebuild phase, the uptimed user could change arbitrary files to be owned by the uptimed user at emerge-time.</p>
    </description>
    <impact type="high">
        <p>The uptimed user could achieve root privileges when the uptimed package is emerged.</p>
    </impact>
    <workaround>
        <p>There is no known workaround at this time.</p>
    </workaround>
    <resolution>
        <p>All uptimed users should upgrade to the latest version:</p>
        
        <code>
          # emerge --sync
          # emerge --ask --oneshot --verbose ">=app-misc/uptimed-0.4.6-r1"
        </code>
