Ubuntu Security Notice USN-1100-1

Posted Mar 31, 2011

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1100-1 - It was discovered that OpenLDAP did not properly check forwarded authentication failures when using a slave server and chain overlay. If OpenLDAP were configured in this manner, an attacker could bypass authentication checks by sending an invalid password to a slave server. 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. 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.

Mandriva Linux Security Advisory 2011-056

Posted Mar 30, 2011

Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2011-056 - chain.c in back-ldap in OpenLDAP 2.4.x before 2.4.24, when a master-slave configuration with a chain overlay and ppolicy_forward_updates is used, allows remote authenticated users to bypass external-program authentication by sending an invalid password to a slave server. bind.cpp in back-ndb in OpenLDAP 2.4.x before 2.4.24 does not require authentication for the root Distinguished Name, which allows remote attackers to bypass intended access restrictions via an arbitrary password. modrdn.c in slapd in OpenLDAP 2.4.x before 2.4.24 allows remote attackers to cause a denial of service via a relative Distinguished Name that contains an empty value for the OldDN field. The updated packages have been patched to correct these issues.
