source-to-image component of Openshift Container Platform before versions atomic-openshift 3.7.53, atomic-openshift 3.9.31 is vulnerable to a privilege escalation which allows the assemble script to run as the root user in a non-privileged container. An attacker can use this flaw to open network connections, and possibly other actions, on the host which are normally only available to a root user.

The remote Red Hat Enterprise Linux CoreOS 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2013 advisory.

  - Routing: Malicous Service configuration can bring down routing for an entire shard. (CVE-2018-1070)

  - openshift-ansible: Incorrectly quoted values in etcd.conf causes disabling of SSL client certificate     authentication (CVE-2018-1085)

  - source-to-image: Builder images with assembler-user LABEL set to root allows attackers to execute     arbitrary code (CVE-2018-10843)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2013 advisory.
