"Using the Codenomicon LDAPv3 test suite, Ilkka Mattila and Tuomas
Salomaki discovered that the slap_modrdn2mods function in modrdn.c in
OpenLDAP does not check the return value from a call to the
smr_normalize function. A remote attacker could use specially crafted
modrdn requests to crash the slapd daemon or possibly execute
arbitrary code. (CVE-2010-0211)

Using the Codenomicon LDAPv3 test suite, Ilkka Mattila and Tuomas
Salomaki discovered that OpenLDAP does not properly handle empty RDN
strings. A remote attacker could use specially crafted modrdn requests
to crash the slapd daemon. (CVE-2010-0212)

In the default installation under Ubuntu 8.04 LTS and later, attackers
would be isolated by the OpenLDAP AppArmor profile for the slapd
daemon.

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
