  * SECURITY UPDATE: Denial of service via resource exhaustion and
    privilege escalation when handling crashes of tainted processes
    (LP: #1726372)
    - When /proc/sys/fs/suid_dumpable is set to 2, do not assume that
      the user and group owning the /proc/<PID>/stat file is the same
      user and group that started the process. Rather check the dump
      mode of the crashed process and do not write a core file if its
      value is 2. Thanks to Sander Bos for discovering this issue!
    - CVE-2017-14177
  * SECURITY UPDATE: Denial of service via resource exhaustion,
    privilege escalation, and possible container escape when handling
    crashes of processes inside PID namespaces (LP: #1726372)
    - Change the method for determining if a crash is from a container
      so that there are no false positives from software using PID
      namespaces. Additionally, disable container crash forwarding by
      ignoring crashes that occur in a PID namespace. This functionality
      may be re-enabled in a future update. Thanks to Sander Bos for
      discovering this issue!
    - CVE-2017-14180
