"The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2022:0952 advisory.

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

    * 389-ds-base: double-free of the virtual attribute context in persistent search (CVE-2021-4091)

    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#2022086)

    * A connection can be erroneously flagged as replication conn during evaluation of an aci with ip bind
    rule (BZ#2022090)

    * DB corruption _entryrdn_insert_key - Same DN (dn: nsuniqueid=ffffffff-ffffffff-ffffffff-
    ffffffff,<SUFFIX>) is already in the entryrdn file (BZ#2022686)

    * CLI needs option to set nsslapd-state (BZ#2040794)

    Users of Red Hat Directory Server 11 are advised to install these updated
    packages.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
