Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:5363 advisory.

- kubernetes: improper validation of URL redirection in the Kubernetes API server allows an attacker- controlled Kubelet to redirect API server requests from streaming endpoints (CVE-2018-1002102)

- kubernetes: compromised node could escalate to cluster level privileges (CVE-2020-8559)

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

Solution
