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: sync_repl NULL pointer dereference in sync_create_state_control() (CVE-2021-3514)

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):

• ACIs are being evaluated against the Replication Manager account in a replication context. (BZ#1968588)

• A connection can be erroneously flagged as replication conn during evaluation of an aci with ip bind rule (BZ#1970791)

• Large updates can reset the CLcache to the beginning of the changelog (BZ#1972721)

• Changelog cache can upload updates from a wrong starting point (CSN) (BZ#1972738)

When using a sync_repl client in 389-ds-base, an authenticated attacker can cause a NULL pointer dereference using a specially crafted query, causing a crash.

It was discovered that 389 Directory Server presented to users, during authentication, an error message which could be used to discover if a certain LDAP DN existed or not. A remote unauthenticated attacker could possibly use this to check the existence of an entry in a LDAP database and expose sensitive information. This issue affected only Ubuntu 20.04 ESM. (CVE-2020-35518)

It was discovered that 389 Directory Server was incorrectly validating data used to access memory addresses. An authenticated attacker using a Syncrepl client could use this issue with a specially crafted query to cause 389 Directory Server to crash, resulting in a denial of service. (CVE-2021-3514)
