Description

The Lightweight Directory Access Protocol (LDAP) is a service that provides a method for looking up information from a central database. The lapd-utils package can be removed with the following command:


$ apt-get remove lapd-utils

Rationale

If the system does not need to act as an LDAP client, it is recommended that the software is removed to reduce the potential attack surface.

Remediation

Shell script

The following script can be run on the host to remediate the issue.

#!/bin/bash

# CAUTION: This remediation script will remove ldap-utils
#	   from the system, and may remove any packages
#	   that depend on ldap-utils. Execute this
#	   remediation AFTER testing on a non-production
#	   system!

DEBIAN_FRONTEND=noninteractive apt-get remove -y "ldap-utils"

Ansible playbook

The following playbook can be run with Ansible to remediate the issue.
