Summary: Red Hat Directory Server 7.1 Service Pack 4: an updated redhat-ds package that fixes a security issue and several bugs is now available. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: RHEL 3 Directory Server AS - i386 RHEL 3 Directory Server ES - i386 RHEL 4 Directory Server AS - i386 RHEL 4 Directory Server ES - i386 3. Description: Red Hat Directory Server is an LDAPv3 compliant server. It was discovered that Red Hat Directory Server 7.1, when running on Red Hat Enterprise Linux, used insecure permissions on certain directories. Local users could replace Java(TM) Archive (JAR) files and run arbitrary code with the privileges of the user running Red Hat Directory Server, or its applications. (CVE-2008-0890) As well, this updated package fixes the followings bugs: * when LDAP operations such as "ldapsearch" were issued while the server was creating a browsing index for the suffix, Red Hat Directory Server hanged. * when a bind operation returned LDAP controls, such as in pass-through authentication, Red Hat Directory Server crashed. * if multiple-simultaneous LDAP operations were issued on entries, which were indexed in a VLV index, Red Hat Directory Server hanged. * minor memory leaks, including memory leaks in replication, SASL, and indexing, have been resolved. * the Red Hat Directory Server crashed during start up if a log rotation file, such as "access.rotationinfo", had a size value of 0 bytes. * on 64-bit platforms, LDAP search operations would intermittently time out, causing them to fail. * it was not possible to send data larger than 512 bytes through SASL GSSAPI. Connections failed with a message decoding error. * when the password lockout option was set, previous log in failures were not cleared from the passwordCount attribute, even after a successful log in. * when an entry had a NULL attribute value for an attribute in a VLV index, editing the entry caused Red Hat Directory Server to crash. * repeatedly removing and adding the same replica and replication agreement, caused Red Hat Directory Server to crash. * random operation failures occurred when multiple-simultaneous SASL operations were initiated. * while VLV indexes were being created, Red Hat Directory Server ignored stop operations. Stop operations sent during index creation hanged. * adding an invalid DN syntax caused Red Hat Directory Server to crash, instead of rejecting the entry. * modify operations that included an invalid attribute value, caused Red Hat Directory server to crash. * malformed member URLs for dynamic groups, such as ones missing the terminal parentheses, caused Red Hat Directory Server to crash. * in the previous redhat-ds package, SASL mappings were hard coded. In this updated package, SASL mappings use regular expressions, that are dynamically generated on start up. A "*" character can no longer be used for the SASL mapping search filter. * repeatedly creating and deleting databases with VLV indexes, caused Red Hat Directory Server to crash. * editing an entry with an attribute with non-ASCII values, and indexed with a substring index, caused Red Hat Directory Server to crash. * in the previous redhat-ds package, SASL operations did not properly switch the SASL I/O function set to the original I/O function set. * during online replication initialization, if the data included any entry larger than 80% of the entry cache size, Red Hat Directory Server crashed. * online-replication initialization hanged endlessly when the import data included two consecutive entries, which totaled more than 80% of the entry cache size. For further information, please refer to the Red Hat Directory Server 7.1 SP4 release notes: http://www.redhat.com/docs/manuals/dir-server/release-notes/7.1SP4/ Users of redhat-ds are advised to upgrade to this updated package, which resolves these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to the system have been applied. To update all RPMs for the particular architecture, run the following command: rpm -Fvh [filenames] where [filenames] is a list of the RPMs to be upgraded. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that it is possible to use wildcards (*.rpm) if the current directory *only* contains the desired RPMs. This update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This starts an interactive process that will result in the appropriate RPMs being upgraded on the system. 5.
