<description>
<p>A Denial of Service flaw was found in the way Xlockmore performed
the passing of arguments to the underlying localtime() call, when the
‘dlock’ mode was used.
</p>
</description>
<impact type="normal">
<p>A local attacker could possibly cause a Denial of Service condition and
potentially obtain unauthorized access to the graphical session,
previously locked by another user.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All Xlockmore users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=x11-misc/xlockmore-5.43"
</code>
</resolution>
