Using the Codenomicon LDAPv3 test suite, Ilkka Mattila and Tuomas
Salomäki 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
Salomäki 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.
