Title:	Ubuntu: Security Advisory (USN-1100-1)
Summary:	The remote host is missing an update for the 'openldap, openldap2.3' package(s) announced via the USN-1100-1 advisory.
Description:	Summary: The remote host is missing an update for the 'openldap, openldap2.3' package(s) announced via the USN-1100-1 advisory. Vulnerability Insight: 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) Affected Software/OS: 'openldap, openldap2.3' package(s) on Ubuntu 8.04, Ubuntu 9.10, Ubuntu 10.04, Ubuntu 10.10. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
