There is no real harm with ptrace and signal rules not being enforced, previous releases did not confine these aspects of process execution; the warning is primarily for the sites where lacking aspects of confinement is a much more important matter.
If I recall correctly, the ptrace and signal features were added to the 14.04 LTS kernel after 3.13.0-16.36 -- probably once this computer boots into a release kernel or newer, these messages will go away on their own. omlk, please consider updating your system as soon as possible; the kernel version you are currently running has a known severe security flaw.
