CVE-2019-6133 (https://nvd.nist.gov/vuln/detail/CVE-2019-6133):
  In PolicyKit (aka polkit) 0.115, the "start time" protection mechanism can
  be bypassed because fork() is not atomic, and therefore authorization
  decisions are improperly cached. This is related to lack of uid checking in
  polkitbackend/polkitbackendinteractiveauthority.c.
