VMware Response to CVE-2018-1002105

Greetings from the VMware Security Response Center!

Yesterday Kubernetes disclosed CVE-2018-1002105 – a critical severity vulnerability in the Kubernetes API server. For more details on the vulnerability please see Kubernetes’ announcement here:

This vulnerability affects the following VMware products:

-VMware Pivotal Container Service (PKS)
-VMware vCloud Director Container Service Extension (CSE)
-Photon OS

There will be no VMware Security Advisory since remediation for these products has already been documented in a separate advisory or the offering’s github page.

For our service offerings that use Kubernetes, mitigations are already in place which have closed down the critical severity attack vector associated with CVE-2018-1002105 while full remediation is in progress.
