    OpenLDAP Software is an open source implementation of the Lightweight
    Directory Access Protocol.

  <description>
    <p>
    Tavis Ormandy of the Gentoo Linux Security Team has discovered that the
    file gencert.sh distributed with the Gentoo ebuild for OpenLDAP does
    not exit upon the existence of a directory in /tmp during installation
    allowing for directory traversal.

  </description>
  <impact type="low">
    <p>
    A local attacker could create a symbolic link in /tmp and potentially
    overwrite arbitrary system files upon a privileged user emerging
    OpenLDAP.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All OpenLDAP users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;net-nds/openldap&quot;</code>
  </resolution>
