The remote Scientific Linux host is missing one or more security
It was found that the 389 Directory Server did not properly restrict
access to entries when the 'nsslapd-allow-anonymous-access'
configuration setting was set to 'rootdse'. An anonymous user could
connect to the LDAP database and, if the search scope is set to BASE,
obtain access to information outside of the rootDSE. (CVE-2013-1897)
This update also fixes the following bugs :
- Previously, the schema-reload plug-in was not
thread-safe. Consequently, executing the
schema-reload.pl script under heavy load could have
caused the ns-slapd process to terminate unexpectedly
with a segmentation fault. Currently, the schema-reload
plug-in is re-designed so that it is thread- safe, and
the schema-reload.pl script can be executed along with
other LDAP operations.
- An out of scope problem for a local variable, in some
cases, caused the modrdn operation to terminate
unexpectedly with a segmentation fault. This update
declares the local variable at the proper place of the
function so it does not go out of scope, and the modrdn
operation no longer crashes.
- A task manually constructed an exact value to be removed
from the configuration if the 'replica-force-cleaning'
option was used. Consequently, the task configuration
was not cleaned up, and every time the server was
restarted, the task behaved in the described manner.
This update searches the configuration for the exact
value to delete, instead of manually building the value,
and the task does not restart when the server is
- Previously, a NULL pointer dereference could have
occurred when attempting to get effective rights on an
entry that did not exist, leading to an unexpected
termination due to a segmentation fault. This update
checks for NULL entry pointers and returns the
appropriate error. Now, attempts to get effective rights
on an entry that does not exist no longer causes
crashes, and the server returns the appropriate error
- A problem in the lock timing in the DNA plug-in caused a
deadlock if the DNA operation was executed with other
plug-ins. This update moves the release timing of the
problematic lock, and the DNA plug-in does not cause the
After installing this update, the 389 server service will be restarted
