RHEL-08-010674 - RHEL 8 must disable storing core dumps.

Information

It is detrimental for operating systems to provide, or install by default, functionality exceeding requirements or mission objectives. These unnecessary capabilities or services are often overlooked and therefore may remain unsecured. They increase the risk to the platform by providing additional attack vectors.

A core dump includes a memory image taken at the time the operating system terminates an application. The memory image could contain sensitive data and is generally useful only for developers trying to debug problems.

Solution

Configure the operating system to disable storing core dumps for all users.

Add or modify the following line in /etc/systemd/coredump.conf:

Storage=none
