RHBA-2015:1998 - Bug Fix Advisory

Topic

Updated 389-ds-base packages that fix several bugs are now available for Red Hat
Enterprise Linux 6.

Description

The 389 Directory Server is an LDAP version 3 (LDAPv3) compliant server. The
base packages include the Lightweight Directory Access Protocol (LDAP) server
and command-line utilities for server administration.

This update fixes the following bugs:

• When multiple replica update vector (RUV) updates were skipped in fractional

replication, RUV was not updated at the end of the session. The next session
then restarted evaluating the same skipped updates. To fix the problem, a system
subentry has been added, which is occasionally updated even when no applicable
changes can be replicated at the time of the update. This prevents the
unnecessary replays. (BZ#1265972)

• Previously, Directory Server did not correctly handle requesting searches for

simple paged results asynchronously in a persistent connection. If one of the
requests was abandoned, the ns-slapd service sometimes terminated unexpectedly.
A patch has been applied to fix the problem, and ns-slapd no longer crashes in
the described situation. (BZ#1268204)

• Directory Server previously did not properly handle freeing search result

objects. A delay occurred between freeing an object and providing the freed
information to the paged results handle. If the handle was released because of a
timeout during the delay, a double free error occurred, which caused the
ns-slapd service to terminate unexpectedly. This update eliminates the mentioned
delay, thus preventing the double free error. As a result, ns-slapd no longer
crashes in this situation. (BZ#1268772)

Users of 389-ds-base are advised to upgrade to these updated packages, which fix
these bugs. After installing this update, the 389 server service will be
restarted automatically.

Solution
