ca-certificates update

A security issue affects these releases of Ubuntu and its derivatives:

The CA certificates in the ca-certificates package were updated.

Software Description:

USN-6105-1 updated ca-certificates. This provides
the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.

of the Mozilla certificate authority bundle.

The problem can be corrected by updating your system to the following
package versions:
