Updated openldap packages that fix security issues are now available for
Red Hat Enterprise Linux 4 and 5.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
OpenLDAP is an open source suite of Lightweight Directory Access Protocol
(LDAP) applications and development tools. LDAP is a set of protocols for
accessing directory services.
These updated openldap packages fix a flaw in the way the OpenLDAP slapd
daemon handled modify and modrdn requests with NOOP control on objects
stored in a Berkeley DB (BDB) storage backend. An authenticated attacker
with permission to perform modify or modrdn operations on such LDAP objects
could cause slapd to crash. (CVE-2007-6698, CVE-2008-0658)
Users of openldap should upgrade to these updated packages, which contain a
backported patch to correct this issue.
