A flaw was found in JSS, where it did not properly free up all memory. Over time, the wasted memory builds up in the server memory, saturating the server’s RAM. This flaw allows an attacker to force the invocation of an out-of-memory process, causing a denial of service.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2024:0774 advisory.

    Red Hat Certificate System (RHCS) is a complete implementation of an enterprise software system designed     to manage enterprise Public Key Infrastructure (PKI) deployments.
