Summary: An update for 389-ds-base is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64le, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: 389 Directory Server is an LDAP version 3 (LDAPv3) compliant server. The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration. Security Fix(es): * A flaw was found in the way 389-ds-base handled authentication attempts against locked accounts. A remote attacker could potentially use this flaw to continue password brute-forcing attacks against LDAP accounts, thereby bypassing the protection offered by the directory server's password lockout policy. (CVE-2017-7551) Bug Fix(es): * In a multi-replication environments, if operations in one back end triggered updates in another back end, the Replica Update Vector (RUV) of the back end was incorrect and replication failed. This fix enables Directory Server to handle Change Sequence Number (CSN) pending lists across multiple back ends. As a result, replication works correctly. (BZ#1476161) * Due to a low default entry cache size value, the Directory Server database had to resolve many deadlocks during resource-intensive tasks. In certain situations, this could result in a "DB PANIC" error and the server no longer responded to requests. After the server was restarted, Directory Server started with a delay to recover the database. However, this recovery could fail, and the database could corrupt. This patch increases the default entry cache size in the nsslapd-cachememsize parameter to 200 MB. As a result, out-of-lock situations or "DB PANIC" errors no longer occur in the mentioned scenario. (BZ#1476162) * Previously, if replication was enabled and a changelog file existed, performing a backup on this master server failed. This update sets the internal options for correctly copying a file. As a result, creating a backup now succeeds in the mentioned scenario. (BZ#1479755) * In certain situations, if the server was previously abruptly shut down, the /etc/dirsrv/<instance_name>/dse.ldif configuration file became corrupted. As a consequence, Directory Server failed to start. With this patch, the server now calls the fsync() function before shutting down to force the file system to write any changes to the disk. As a result, the configuration no longer becomes corrupted, regardless how the server gets stopped. (BZ#1479757) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing this update, the 389 server service will be restarted automatically. 5. Bugs fixed (https://bugzilla.redhat.com/): 1476161 - 1.3.5.10-20 replication halt - pending list first CSN not committed, pending list increasing [rhel-7.4.z] 1476162 - Change the retrochangelog default cache size. And also if possible, the default caches.
