Red Hat Security Advisory: redhat-ds:11 security and bug fix update
Severity
Moderate
Notes
Topic: An update for the redhat-ds:11 module is now available for Red Hat Directory Server 11.2 for RHEL 8.
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.
Details: Red Hat Directory Server is an LDAPv3-compliant directory server. The suite of packages includes the Lightweight Directory Access Protocol (LDAP) server, as well as command-line utilities and Web UI packages for server administration.
Security Fix(es):
* 389-ds-base: information disclosure during the binding of a DN (CVE-2020-35518) (BZ#1905565)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* The UI become unresponsive when an error occured (BZ#1751082)
* The python-lib389 class Accounts displayed an error during delete operations (BZ#1859215)
* The server version number has been added to the UI (BZ#1859288)
* Searches by an unauthorized client can no longer determine if an entry exists or not by the result code (BZ#1925537)
* Changes made on the Server Tuning page in the web console are now correctly reflected (BZ#1927051)
* Adding new schema using dsconf no longer displayes a "values has to be a tuple" error (BZ#1937036)
Users of Red Hat Directory Server 11 are advised to install these updated packages.

When binding against a DN during authentication, the reply from 389-ds-base will be different whether the DN exists or not. This can be used by an unauthenticated attacker to check the existence of an entry in the LDAP database.
