"The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2024:1372 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: A heap overflow flaw that leads to a denial of service when writing a value larger than 256
    chars in log_entry_attr. (CVE-2024-1062)

    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) and Enhancement(s):

    * Adequate etime and no error Retry count exceeded on bind, add, delete, and modify operations from
    revert_cache (BZ#2268136)

    * RHDS LDAP server segmentation works as expected (BZ#2268138)

    * Slow search when using filter with a virtual attribute (eg: nsRole ). (BZ#2265536)

    * RHDS healthcheck incorrectly complains about missing backend definitions. (BZ#2265537)

    * Paged search impacts performance (BZ#2265544)

    * dtablesize being set to soft maxfiledescriptor limit causing massive slowdown in large environments
    (BZ#2265538)

    * dsconf should prevent setting the replicaID for hub and consumer roles. (BZ#2265543)

    * bdb_start - Detected Disorderly Shutdown directory server is not starting (BZ#2265540)

    * After an upgrade the LDAP server wont start if nsslapd-conntablesize is present in the dse.ldif file
    (BZ#2265539)

    * [RFE] Required to support both at a same time account inactivity and expiration. (BZ#2265541)
