-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: 389-ds-base security and bug fix update Advisory ID: RHSA-2013:0628-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0628.html Issue date: 2013-03-11 CVE Names: CVE-2013-0312 ===================================================================== 1. Summary: Updated 389-ds-base packages that fix one security issue and multiple bugs are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: The 389 Directory Server is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration. 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) The CVE-2013-0312 issue was discovered by Thierry Bordaz of Red Hat. This update also fixes the following bugs: * After an upgrade from Red Hat Enterprise 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. (BZ#910994) * 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 modify_update_last_modified_attr() function. (BZ#910995) * 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. (BZ#910996) * 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. (BZ#911467) * 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. (BZ#911468) * 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. (BZ#911469) * 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. (BZ#911474) * 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. (BZ#914305) All 389-ds-base users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the 389 server service will be restarted automatically. 4.
