"The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2024:4092 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: potential denial of service via specially crafted kerberos AS-REQ request (CVE-2024-3657)
    (2267976)

    * 389-ds-base: Malformed userPassword may cause crash at do_modify in slapd/modify.c (CVE-2024-2199)
    (2274401)

    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):

    * One level scoped search now returns a subsuffix correctly (BZ#2292903)

    * Improved performance of filter component evaluation when tested against a large value set, such as group
    members (BZ#2293001)

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
