+ <background>
+ <p>
+ OpenLDAP Software is an open source implementation of the Lightweight
+ Directory Access Protocol.

+ <description>
+ <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 "&gt;=net-nds/openldap-2.3.41"</code>
