The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2757 advisory.

    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):

    * 389-ds-base: race condition on reference counter leads to DoS using persistent search (CVE-2018-10850)

    * 389-ds-base: ldapsearch with server side sort allows users to cause a crash (CVE-2018-10935)

    * 389-ds-base: Server crash through modify command with large DN (CVE-2018-14624)

    * 389-ds-base: Crash in delete_passwdPolicy when persistent search connections are terminated unexpectedly     (CVE-2018-14638)

    For more details about the security issue(s), including the impact, a CVSS score, and other related     information, refer to the CVE page(s) listed in the References section.

    The CVE-2018-10850 issue was discovered by Thierry Bordaz (Red Hat) and the CVE-2018-14638 issue was     discovered by Viktor Ashirov (Red Hat).

    Bug Fix(es):

    * Previously, the nucn-stans framework was enabled by default in Directory Server, but the framework is     not stable. As a consequence, deadlocks and file descriptor leaks could occur. This update changes the     default value of the nsslapd-enable-nunc-stans parameter to off. As a result, Directory Server is now     stable. (BZ#1614836)

    * When a search evaluates the shadowAccount entry, Directory Server adds the shadow attributes to the     entry. If the fine-grained password policy is enabled, the shadowAccount entry can contain its own     pwdpolicysubentry policy attribute. Previously, to retrieve this attribute, the server started an     internal search for each shadowAccount entry, which was unnecessary because the entry was already known     to the server. With this update, Directory Server only starts internal searches if the entry is not known.
    As a result, the performance of searches, such as response time and throughput, is improved. (BZ#1615924)
