FINAL RESULTS:

data/dde-calendar-5.0.1/src/calendarwindow.cpp:294:68:  [4] (shell) system:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.

data/dde-calendar-5.0.1/src/main.cpp:37:24:  [2] (misc) open:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
