 1. If the hostname is greater than 64 characters there will be issues with certificates. It is highly recommended to use hostname shorter than 64 characters or use SANs for hostnames in the certificates.
 2. The MarkLogic Docker image must be run in privileged mode. At the moment if the image isn't run as privileged many calls that use sudo during the startup script will fail due to lack of required permissions as the image will not be able to create a user with the required permissions.
 3. The latest released version of CentOS 7 has known security vulnerabilities with respect to glib2 CVE-2016-3191, CVE-2015-8385, CVE-2015-8387, CVE-2015-8390, CVE-2015-8394, CVE-2016-3191, glibc CVE-2019-1010022, pcre CVE-2015-8380, CVE-2015-8387, CVE-2015-8390, CVE-2015-8393, CVE-2015-8394, SQLite CVE-2019-5827. These libraries are included in the CentOS base image but, to-date, no fixes have been made available. Even though these libraries may be present in the base image that is used by MarkLogic Server, they are not used by MarkLogic Server itself, hence there is no impact or mitigation required.
-4. The latest released version of fluent/fluent-bit:2.2.2 has known security vulnerabilities with respect to libcom-err2 CVE-2022-1304, libgcrypt20 CVE-2021-33560, libgnutls30 CVE-2024-0567, libldap-2.4-2 CVE-2023-2953, libzstd1 CVE-2022-4899, zlib1g CVE-2023-45853. These libraries are included in the Debian base image but, to-date, no fixes have been made available. For libpq5 CVE-2024-0985, we wait for a future upgrade of the fluent-bit image to include the fix. We will provide updates and mitigation strategies as soon as more information becomes available.
+4. The latest released version of fluent/fluent-bit:3.1.1 has known high and critical security vulnerabilities. If you decide to enable the log collection feature, choose and deploy the fluent-bit or an alternate image with no vulnerabilities as per your requirements.
 5. The latest released version of redhat/ubi9:9.3 has known security vulnerabilities with respect to setuptools GHSA-r9hx-vwmv-q579. We wait for a future upgrade of the redhad ubi image to include the fix.
 6. The security context “allowPrivilegeEscalation” is set to TRUE by default in values.yaml file and cannot be changed to run the current MarkLogic container. Work is in progress to run MarkLogic container in "rootless" mode.
