It was discovered that OpenLDAP did not properly check forwarded
authentication failures when using a consumer server and chain overlay. If
OpenLDAP were configured in this manner, an attacker could bypass
authentication checks by sending an invalid password to a consumer server.
(CVE-2011-1024)
It was discovered that OpenLDAP did not properly perform authentication
checks to the rootdn when using the back-ndb backend. An attacker could
exploit this to access the directory by sending an arbitrary password.
Ubuntu does not ship OpenLDAP with back-ndb support by default. This issue
did not affect Ubuntu 8.04 LTS. (CVE-2011-1025)
It was discovered that OpenLDAP did not properly validate modrdn requests.
An unauthenticated remote user could use this to cause a denial of service
via application crash. (CVE-2011-1081)
