  <description>
    <p>
    XScreenSaver incorrectly handles the results of the getpwuid() function
    in drivers/lock.c when using directory servers during a network outage.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local user can crash XScreenSaver by preventing network connectivity
    if the system uses a remote directory service for credentials such as
    NIS or LDAP, which will unlock the screen.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All XScreenSaver users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=x11-misc/xscreensaver-5.02&quot;</code>
  </resolution>
