Test ID:	1.3.6.1.4.1.25623.1.0.69380
Category:	Ubuntu Local Security Checks
Title:	Ubuntu USN-1100-1 (openldap2.3)
Summary:	Ubuntu USN-1100-1 (openldap2.3)
Description:	The remote host is missing an update to openldap2.3 announced via advisory USN-1100-1. Details follow: 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. (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) Solution: The problem can be corrected by upgrading your system to the following package versions: Ubuntu 8.04 LTS: slapd 2.4.9-0ubuntu0.8.04.5 Ubuntu 9.10: slapd 2.4.18-0ubuntu1.2 Ubuntu 10.04 LTS: slapd 2.4.21-0ubuntu5.4 Ubuntu 10.10: slapd 2.4.23-0ubuntu3.5 In general, a standard system update will make all the necessary changes. http://www.securityspace.com/smysecure/catid.html?in=USN-1100-1 Risk factor : High
