A flaw was found in the way LDAPv3 control data was handled by 389
Directory Server. If a malicious user were able to bind to the
directory (even anonymously) and send an LDAP request containing
crafted LDAPv3 control data, they could cause the server to crash,
denying service to the directory. (CVE-2013-0312)
This update also fixes the following bugs :
- After an upgrade from Scientific Linux 6.3 to version
6.4, the upgrade script did not update the schema file
for the PamConfig object class. Consequently, new
features for PAM such as configuration of multiple
instances and pamFilter attribute could not be used
because of the schema violation. With this update, the
upgrade script updates the schema file for the PamConfig
object class and new features function properly.
- Previously, the valgrind test suite reported recurring
memory leaks in the modify_update_last_modified_attr()
function. The size of the leaks averaged between 60-80
bytes per modify call. In environments where modify
operations were frequent, this caused significant
problems. Now, memory leaks no longer occur in the
- The Directory Server (DS) failed when multi-valued
attributes were replaced. The problem occurred when
replication was enabled, while the server executing the
modification was configured as a single master and there
was at least one replication agreement. Consequently,
the modification requests were refused by the master
server, which returned a code 20 'Type or value exists'
error message. These requests were replacements of
multi-valued attributes, and the error only occurred
when one of the new values matched one of the current
values of the attribute, but had a different letter
case. Now, modification requests function properly and
no longer return code 20 errors.
- The DNA (distributed numeric assignment) plug-in, under
certain conditions, could log error messages with the
'DB_LOCK_DEADLOCK' error code when attempting to create
an entry with a uidNumber attribute. Now, DNA handles
this case properly and errors no longer occur during
attempts to create entries with uidNumber attributes.
- Posix Winsync plugin was calling an internal modify
function which was not necessary. The internal modify
call failed and logged an error message
'slapi_modify_internal_set_pb: NULL parameter' which was
not clear. This patch stops calling the internal modify
function if it is not necessary and the cryptic error
message is not observed.
- Previously, under certain conditions, the dse.ldif file
had 0 bytes after a server termination or when the
machine was powered off. Consequently, after the system
was brought up, a DS or IdM system could be unable to
restart, leading to production server outages. Now, the
server mechanism by which the dse.ldif is written is
more robust, and tries all available backup dse.ldif
files, and outages no longer occur.
- Due to an incorrect interpretation of an error code, a
directory server considered an invalid chaining
configuration setting as the disk full error and shut
down unexpectedly. Now, a more appropriate error code is
in use and the server no longer shuts down from invalid
chaining configuration settings.
- While trying to remove a tombstone entry, the ns-slapd
daemon terminated unexpectedly with a segmentation
fault. With this update, removal of tombstone entries no
longer causes crashes.
After installing this update, the 389 server service will be restarted
