  shadow (1:4.2-3.1ubuntu5.3) xenial-security; urgency=medium

  * REGRESSION UPDATE: The patch for CVE-2017-2616 introduced a regression.
    If su received a signal like SIGTERM it wasn't propagated to the child.
    - debian/patches/CVE-2017-2616-regression.patch: Do not reset the
      pid_child to 0 if the child process is still running.
    Thanks to Tobias Stoeckmann for the fix and Radu Duta for the report.
