Ubuntu 5.10 / 6.06 LTS / 6.10 : openldap2.2 vulnerability (USN-384-1)

medium Nessus Plugin ID 27967

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Evgeny Legerov discovered that the OpenLDAP libraries did not correctly truncate authcid names. This situation would trigger an assert and abort the program using the libraries. A remote attacker could send specially crafted bind requests that would lead to an LDAP server denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ldap-utils, libldap-2.2-7 and / or slapd packages.
