commit 9737baf530d80eff19d46a5feb130d3064d47d64
Author: Daniel P. Berrangé <berrange@redhat.com>
Date:   Wed Apr 3 15:00:50 2019 +0100

    remote: enforce ACL write permission for getting guest time & hostname
    
    Getting the guest time and hostname both require use of guest agent
    commands. These must not be allowed for read-only users, so the
    permissions check must validate "write" permission not "read".
    
    Fixes CVE-2019-3886
