Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2019:3403 advisory.

  - The containers/image library used by the container tools Podman, Buildah, and Skopeo in Red Hat Enterprise     Linux version 8 and CRI-O in OpenShift Container Platform, does not enforce TLS connections to the     container registry authorization service. An attacker could use this vulnerability to launch a MiTM attack     and steal login credentials or bearer tokens. (CVE-2019-10214)

  - ip_reass in ip_input.c in libslirp 4.0.0 has a heap-based buffer overflow via a large packet because it     mishandles a case involving the first fragment. (CVE-2019-14378)

  - Cloud Native Computing Foundation (CNCF) CNI (Container Networking Interface) 0.7.4 has a network firewall     misconfiguration which affects Kubernetes. The CNI 'portmap' plugin, used to setup HostPorts for CNI,     inserts rules at the front of the iptables nat chains; which take precedence over the KUBE- SERVICES     chain. Because of this, the HostPort/portmap rule could match incoming traffic even if there were better     fitting, more specific service definition rules like NodePorts later in the chain. The issue is fixed in     CNI 0.7.5 and Kubernetes 1.11.9, 1.12.7, 1.13.5, and 1.14.0. (CVE-2019-9946)

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

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2019-4593 advisory.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:3403 advisory.

    The container-tools module contains tools for working with containers, notably podman, buildah, skopeo,     and runc.

    Security Fix(es):

    * QEMU: slirp: heap buffer overflow during packet reassembly (CVE-2019-14378)

    * containers/image: not enforcing TLS when sending username+password credentials to token servers leading     to credential disclosure (CVE-2019-10214)
