"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.");
