Examining data/xcompmgr-1.1.8/xcompmgr.c

FINAL RESULTS:

data/xcompmgr-1.1.8/xcompmgr.c:2075:17:  [3] (buffer) getopt:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
    while ((o = getopt (argc, argv, "D:I:O:d:r:o:l:t:scnfFCaS")) != -1)
data/xcompmgr-1.1.8/xcompmgr.c:790:6:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	    memcpy (&pixmap, prop, 4);
data/xcompmgr-1.1.8/xcompmgr.c:1301:2:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	memcpy (&i, data, sizeof (unsigned int));
data/xcompmgr-1.1.8/xcompmgr.c:1339:2:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	memcpy (&a, data, sizeof (Atom));
data/xcompmgr-1.1.8/xcompmgr.c:1769:10:  [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.
  static char	buf[128];
data/xcompmgr-1.1.8/xcompmgr.c:1779:5:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
    sprintf (buf, "Shape %d", kind);
data/xcompmgr-1.1.8/xcompmgr.c:1842:12:  [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.
    static char buffer[256];
data/xcompmgr-1.1.8/xcompmgr.c:1909:12:  [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.
    static char	buf[128];
data/xcompmgr-1.1.8/xcompmgr.c:1930:2:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
	sprintf (buf, "Event %d", ev->type);
data/xcompmgr-1.1.8/xcompmgr.c:2082:19:  [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).
	    fade_delta = atoi (optarg);
data/xcompmgr-1.1.8/xcompmgr.c:2121:21:  [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).
	    shadowRadius = atoi (optarg);
data/xcompmgr-1.1.8/xcompmgr.c:2127:22:  [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).
	    shadowOffsetX = atoi (optarg);
data/xcompmgr-1.1.8/xcompmgr.c:2130:22:  [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).
	    shadowOffsetY = atoi (optarg);
data/xcompmgr-1.1.8/xcompmgr.c:1882:24:  [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).
	     ev->error_code, (strlen (name) > 0) ? name : "unknown",
