Description

The mcstransd daemon provides category label information to client processes requesting information. The label translations are defined in /etc/selinux/targeted/setrans.conf. The mcstrans package can be removed with the following command:


$ sudo yum erase mcstrans

Rationale

Since this service is not used very often, disable it to reduce the amount of potentially vulnerable code running on the system.

Remediation

Shell script

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

#!/bin/bash

# Remediation is applicable only in certain platforms
if [ ! -f /.dockerenv ] && [ ! -f /run/.containerenv ]; then

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

if rpm -q --quiet "mcstrans" ; then

    yum remove -y "mcstrans"

fi

else
    >&2 echo 'Remediation is not applicable, nothing was done'
fi
