Language:

Synopsis

The remote Red Hat host is missing one or more security updates for OpenShift Container Platform 3.11 atomic-openshift.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:3905 advisory.

 - kubernetes: `kubectl cp` allows for arbitrary file write via double symlinks (CVE-2019-11251)

 - kubernetes: YAML parsing vulnerable to Billion Laughs attack, allowing for remote denial of service (CVE-2019-11253)

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