FINAL RESULTS:

data/cairodevice-2.28.2/src/cairoDevice.c:341:26:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
  R_WriteConsole(prompt, strlen(prompt));

  perform an over-read (it could cause a crash if unprotected) (CWE-126).
        R_WriteConsole(cprompt, strlen(cprompt));
data/cairodevice-2.28.2/src/gtk.c:82:10:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
