The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:4209 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(s):
* 389-ds-base: Potential denial of service via specially crafted kerberos AS-REQ request (CVE-2024-3657) (BZ#2274401)
* 389-ds-base: Authenticated user can cause a server failure while modifying `userPassword` using malformed input (CVE-2024-2199) (BZ#2267976)
* 389-ds-base: Denial of service when writing a value larger than 256 chars in log_entry_attr (CVE-2024-1062) (BZ#2261879)
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):
* Directory Server now flushes the entry cache less frequently (BZ#2268177)
* The `ns-slapd` binary is now linked with the thread-safe `libldap_r` library, no longer causing segmentation fault (BZ#2264534)
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.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
