There is a possible DoS vulnerability in the multipart parser in Rack before 2.0.6. Specially crafted requests can cause the multipart parser to enter a pathological state, causing the parser to use CPU resources disproportionate to the request size.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:3172 advisory.

    Red Hat Satellite is a systems management tool for Linux-based infrastructure. It allows for provisioning,     remote management, and monitoring of multiple Linux deployments with a single centralized tool.

    Security Fix(es):

    * rubygem-rack: Buffer size in multipart parser allows for denial of service (CVE-2018-16470)

    * dom4j: XML Injection in Class: Element. Methods: addElement, addAttribute which can impact the integrity     of XML documents (CVE-2018-1000632)

    * foreman: authorization bypasses in foreman-tasks leading to information disclosure (CVE-2019-10198)

    * katello: registry credentials are captured in plain text during repository discovery (CVE-2019-14825)
