Synopsis
Moderate: 389-ds-base security, bug fix, and enhancement update
Type/Severity
Security Advisory: Moderate
Topic
Updated 389-ds-base packages that fix one security issue, numerous bugs,
and add various enhancements are now available for Red Hat Enterprise
Linux 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.
Description
The 389-ds-base packages provide 389 Directory Server, which is an LDAPv3
compliant server. The base packages include the Lightweight Directory
Access Protocol (LDAP) server and command-line utilities for server
administration.
A flaw was found in the way 389 Directory Server enforced ACLs after
performing an LDAP modify relative distinguished name (modrdn) operation.
After modrdn was used to move part of a tree, the ACLs defined on the moved
(Distinguished Name) were not properly enforced until the server was
restarted. This could allow LDAP users to access information that should be
restricted by the defined ACLs. (CVE-2012-4450)
This issue was discovered by Noriko Hosoi of Red Hat.
These updated 389-ds-base packages include numerous bug fixes and
enhancements. Space precludes documenting all of these changes in this
advisory. Users are directed to the Red Hat Enterprise Linux 6.4
Technical Notes, linked to in the References, for information on the most
significant of these changes.
All users of 389-ds-base are advised to upgrade to these updated packages,
which correct this issue and provide numerous bug fixes and enhancements.
After installing this update, the 389 server service will be restarted
automatically.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
