"This update for backintime to version 1.1.20 fixes several issues.

These security issues were fixed :

  - CVE-2017-7572: The _checkPolkitPrivilege function in
    serviceHelper.py in backintime used a deprecated polkit
    authorization method (unix-process) that is subject to a
    race condition (time of check, time of use)
    (bsc#1032717).

  - Don't store passwords given to polkit helper

  - boo#1007723: General security hardening measures 

These non-security issues were fixed :

  - Delete udev configuration files on uninstall

  - Merge doc subpackage into main package"
