Examining data/xrestop-0.4+git20130926/xrestop.c

FINAL RESULTS:

data/xrestop-0.4+git20130926/xrestop.c:57:28:  [4] (format) fprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
#define DBG(txt, args... ) fprintf(stderr, txt , ##args )
data/xrestop-0.4+git20130926/xrestop.c:505:3:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
  char pretty_pixmap_bytes[16] = { 0 };
data/xrestop-0.4+git20130926/xrestop.c:506:3:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
  char pretty_other_bytes[16]  = { 0 };

  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the

  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use

data/xrestop-0.4+git20130926/xrestop.c:678:17:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
	  app->delay = atoi(argv[i]);
