Most good programmers do programming not because they expect to get paid or get adulation by the public, but because it is fun to program. – Linus Torvalds

Please update your util-linux package to version 2.29.2.

A recently released update to Util-Linux has address a security vulnerability, assigned with CVE-2017-2616.

It is possible for any local user to send SIGKILL to other processes with root privileges. To exploit this, the user must be able to perform su with a successful login. SIGKILL can only be sent to processes which were executed after the su process. It is not possible to send SIGKILL to processes which were already running.
