+    <p>
+    The following errors have been discovered in OpenLDAP:
+    </p>
+    <ul>
+    <li>
+    Tony Blake discovered an error which exists within the normalisation of
+    "objectClasses" (CVE-2007-5707).</li>
+    <li>
+    Thomas Sesselmann reported that, when running as a proxy-caching server
+    the "add_filter_attrs()" function in servers/slapd/overlay/pcache.c
+    does not correctly NULL terminate "new_attrs" (CVE-2007-5708).</li>
+    <li>
+    A double-free bug exists in attrs_free() in the file
+    servers/slapd/back-bdb/modrdn.c, which was discovered by Jonathan
+    Clarke (CVE-2008-0658).</li>
+    </ul>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker can cause a Denial of Serivce by sending a malformed
+    "objectClasses" attribute, and via unknown vectors that prevent the
+    "new_attrs" array from being NULL terminated, and via a modrdn
+    operation with a NOOP (LDAP_X_NO_OPERATION) control.
+    </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;&gt;=net-nds/openldap-2.3.41&quot;</code>
