There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - etcd versions 3.2.x before 3.2.26 and 3.3.x before 3.3.11 are vulnerable to an improper authentication
    issue when role-based access control (RBAC) is used and client-cert-auth is enabled. If an etcd client
    server TLS certificate contains a Common Name (CN) which matches a valid RBAC username, a remote attacker
    may authenticate as that user with any valid (trusted) client certificate in a REST API request to the
    gRPC-gateway. (CVE-2018-16886)

An update of the etcd package has been released.
