FINAL RESULTS:

data/pagemon-0.01.21/pagemon.c:387:6:  [4] (buffer) sscanf:
  The scanf() family's %s operation, without a limit specification, permits
  buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
  different input function. If the scanf format is influenceable by an
  attacker, it's exploitable.
	if (sscanf(ptr, "%" SCNu64 " %*u %" SCNu64, minor_flt, major_flt) != 2)

data/pagemon-0.01.21/pagemon.c:560:8:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.

  of all string inputs.
