3. Bugs Fixed in Directory Server 7.1 SP7
The following are some of the most important bugs fixed for Directory Server 7.1 SP7. Along with this
service pack, some erratas have been issued for Red Hat Directory Server, fixing important security
and performance issues. The complete list of erratas issued for Red Hat Directory Server 7.1 SP7 for
Red Hat Enterprise Linux is available through Red Hat Network at ht-
tps://1rhn.redhat.com/1errata/1rhel-dirserv-71-errata.html.
Red Hat Directory Server 7.1 SP7 is released as an update as Erratum RHSA 2008:0596, which is
asociated with Bugzilla #453229.
Bug Number Alternate ID Description
233642
The change sequence numbers in multi-master replication had
a built-in skew to accommodate differences in the clocks on
master servers. However, this skew could grow under some
circumstances to the point that it falsely hit the maximum allowed skew (one day by default) and stopped replication entirely. Because the problem was in the timestamps of the CSNs

Bug Number Alternate ID Description
for the masters, replication could not be easily restarted. The
severity of the problem increased with the number of updates
made to the Directory Server.
This has been fixed.
440333
There were uninitialized variables in plug-ins for logging and
access controls. These have been fixed.
448831
CVE2008-2930
454065
A flaw in the way the Directory Server handled LDAP search
requests using patterns could allow a remote attacker to cause
the Directory Server to use large amounts of CPU time. Pattern
searches were not restricted by normal directory search time
limits. If the attacker had access to LDAP service, he could
create a search request with a search pattern that matched
specially-crafted data records, running searches without time
limits and consuming CPU time.
The Directory Server has been updated to apply the
nsslapd-timelimit attribute to the pattern search query
run time. This attribute has a default limit of 3600 seconds (one
hour). To shorten the time limit, modify the nsslapd-
timelimit parameter in cn=config. For example:
ldapmodify -D "cn=Directory Manager" -w
password
dn: cn=config
changetype: modify
replace: nsslapd-timelimit
nsslapd-timelimit: 30
450973
Password policy attributes are not replicated by default.
However, if a password attribute such as accountunlock-
time was added to an entry, the server would attempt to replicate that attribute, which would cause an error. Rather than
correctly processing the error, replication would fail.
This has been fixed.
452169
In replication scenarios, if an attribute value was scheduled to
be deleted and also was indexed or had an attribute subtype
which was indexed, the Directory Server would crash during
the index operation.
This has been fixed.
453916
413531
453921
CVE2008-2928
Several Directory Server CGI applications were affected by a
buffer overflow flaw in the routine which parses Accept Language HTTP headers. The web services could be configured
to allow acceptable language configurations which caused the

Bug Number Alternate ID Description
web services to quit functioning and crash the server. A remote
attacker with access to the Administration Server web interface
could exploit the flaw to crash those CGIs or, possibly, to execute arbitrary code with the privileges of the Administration
Server, which typically runs as the root user on the host machine.
This has been fixed.
454328
The Directory Server crashed on some looping operations,
such as recursively adding groups as members to other groups
(Group A becomes a member of Group B, which becomes a
member of Group C, and so on). Because the stack size for
64-bit systems was hard-coded to 256KB, relatively small
loops could still overflow the stack.
This has been fixed.
454621
245248
454658
CVE2008-2929
The Directory Server Gateway and Administration Server Express interfaces had scripting issues cause by improperly parsing a percent (%)-escaped value provided by a user. A remote
attacker could exploit this flaw to execute cross-site attacks
against Directory Server users or administrators who used
those web services.
These errors have been fixed.
458171
On HP-UX, when running an approximate search, the search
code could return an error code 3, which corresponds to the
LDAP error code for exceeding the search time limit. This
meant that an appropximate search could end prematurely with
a timeout error, even though the time limit had not been
reached.
This error has been fixed.
458506
CVE2008-3283
458692
458977
There was a memory leak error in the SASL bind code. This
error was difficult to trigger in real-world scenarios because it
required sending a 0-valued password for a SASL bind, but it
could be triggered by an anonymous user.
This error has been fixed.
458507
CVE2008-3283
458692
458977
There was a memory leak error when changing the password
storage scheme. This error could only be triggered by an admin user, not an anonymous user.
This error has been fixed.
458510
CVE2008-3283
There was a memory leak error when a user attempted to
change a password; if the given DN for the password change

was null, the operation defaulted to changing the password for
the bind DN, and there was a small memory leak at that transition. This could be triggered by an anonymous user.
This error has been fixed.
458666
CVE2008-3283
458692
458977
When trivial word checking was enabled in the password
policy, there was a small memory leak when trivial word checking was run when a user changed his password.
This error has been fixed.
458668
CVE2008-3283
458692
458977
There was a memory leak error in the SASL mapping code
with the regular expressions which are used with the identity
mapping to look up a user's bind DN based on the user and
user realm.
This error has been fixed.
458675
CVE2008-3283
458692
458977
There was a memory leak error in how Directory Server
handled value sets where there were several duplicate, nonsequential values added to an attribute, such as adding foo,
bar, bat, foo. This leak could only be triggered by an authenticated user to the Directory Server who had the rights to modify
attributes in an entry, including self-write access, and if replication was being used.
This error has been fixed.
458677
CVE2008-3283
458692
458977
There was a memory leak error in the index code for searches
which were run against the index with a range or with a matching rule.
This error has been fixed.

4. Known Issues
The following are some of the most important known issues in Directory Server 7.1 SP7. When possible, supported workarounds are also described.
Bug Number Description Workaround
171140 Upgrading the Windows Sync service on the
Windows server from version 7.1 to version
7.1 SP1 or higher (including 7.1 SP7) requires
two things:
•
Rebooting the Windows machine.
Known Issues

Page 12
Bug Number Description Workaround
•
Performing a full manual resynchronization.
To manually synchronize Active Directory
and Directory Server, open the Directory
Server Console, and, in the Configuration
tab, click the Replication folder, select the
database, and the right-click on the synchronization agreement.
311851 SASL mapping entries are dynamically created
and stored in the configuration file at the instance generation. The mapping entries are
associated with the primary suffix. If a second
root suffix is added and entries under the
second suffix need to be mapped by SASL
mapping, there are no mapping entries created
for them. The original SASL mapping entries
point to the first suffix.
Manually create SASL mapping entries that are associated with the second suffix.
400341 If a user other than the admin user logs into
the Console and attempts to change the admin
user's password, the password is not properly
updated.
Only change the admin user
password through the Console
when logged in as the admin
user.
429631 If a Windows directory is synchronized with a
virtual directory tree in Red Hat Directory Server, then the Red Hat Directory Server crashes
when synchronization is initiated.
Do not use virtual branch
entries as the synchronization
database.
