"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2020:3541 advisory.

    Jenkins is a continuous integration server that monitors executions of repeated jobs, such as building a
    software project or jobs run by cron. The Matrix Project is a module which handles creating Jenkins multi-
    configuration projects (matrix projects). Matrix Authorization allows configuring the lowest level
    permissions, such as starting new builds,
    configuring items, or deleting them, individually.

    Python-RSA is a RSA implementation in Python. It can be used as a Python
    library as well as the commandline utility.

    Ansible is a SSH-based configuration management, deployment, and task execution system. The openshift-
    ansible packages contain Ansible code and playbooks for installing and upgrading OpenShift Container
    Platform 3.

    Security Fix(es):

    * jenkins: Stored XSS vulnerability in job build time trend (CVE-2020-2220)

    * jenkins: Stored XSS vulnerability in upstream cause (CVE-2020-2221)

    * jenkins: Stored XSS vulnerability in 'keep forever' badge icons (CVE-2020-2222)

    * jenkins: Stored XSS vulnerability in console links (CVE-2020-2223)

    * jenkins-2-plugins/matrix-project: Stored XSS vulnerability in single axis builds tooltips
    (CVE-2020-2224)

    * jenkins-2-plugins/matrix-project: Stored XSS vulnerability in multiple axis builds tooltips
    (CVE-2020-2225)

    * jenkins-2-plugins/matrix-auth: Stored XSS vulnerability in Matrix Authorization Strategy Plugin
    (CVE-2020-2226)

    * jenkins-jira-plugin: plugin information disclosure (CVE-2019-16541)

    * python-rsa: decryption of ciphertext leads to DoS (CVE-2020-13757)

    * openshift-ansible: cors allowed origin allows changing url protocol (CVE-2020-1741)
