Description Vlad K. 2018-12-05 18:06:42 UTC 
* CVE-2018-19788

  https://gitlab.freedesktop.org/polkit/polkit/issues/74

  "A flaw was found in PolicyKit (aka polkit) 0.115 that allows a user with a
  uid greater than INT_MAX to successfully execute any systemctl command."
  -- CVE listing

According to the original issue comments though, this vuln is not only about systemctl commands, but "any PK services".
