FINAL RESULTS:

data/radeontop-1.2/detect.c:94:3:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
		strcpy(drm_name, ver->name);
data/radeontop-1.2/detect.c:97:20:  [4] (race) access:
  This usually indicates a security flaw. If an attacker can change anything
  along the path between the call to access() and the file's actual use
  (e.g., by moving files), the attacker can exploit the race condition
  (CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
  and try to open the file directly.
	if (drm_fd < 0 && access("/dev/ati/card0", F_OK) == 0) // fglrx path
data/radeontop-1.2/radeontop.c:114:11:  [3] (buffer) getopt_long:
  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.
		int c = getopt_long(argc, argv, "b:cd:hi:l:mt:v", opts, NULL);
data/radeontop-1.2/detect.c:34:1:  [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 drm_name[10] = ""; // should be radeon or amdgpu
data/radeontop-1.2/detect.c:74:2:  [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 busid[32];
data/radeontop-1.2/detect.c:98:12:  [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).
		drm_fd = open("/dev/ati/card0", O_RDWR);
data/radeontop-1.2/detect.c:113:13:  [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).
		int mem = open("/dev/mem", O_RDONLY);
data/radeontop-1.2/dump.c:60:7:  [2] (misc) fopen:
  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).
		f = fopen(file, "a");
data/radeontop-1.2/include/gettext.h:193:3:  [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 msg_ctxt_id[msgctxt_len + msgid_len];
data/radeontop-1.2/include/gettext.h:195:3:  [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 buf[1024];
data/radeontop-1.2/include/gettext.h:203:7:  [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 (msg_ctxt_id, msgctxt, msgctxt_len - 1);
data/radeontop-1.2/include/gettext.h:205:7:  [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 (msg_ctxt_id + msgctxt_len, msgid, msgid_len);
data/radeontop-1.2/include/gettext.h:239:3:  [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

data/radeontop-1.2/include/gettext.h:241:3:  [2] (buffer) char:

      memcpy (msg_ctxt_id + msgctxt_len, msgid, msgid_len);
data/radeontop-1.2/radeontop.c:123:13:  [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).

				dumpinterval = atoi(optarg);
data/radeontop-1.2/dump.c:67:3:  [1] (obsolete) usleep:
  This C routine is considered obsolete (as opposed to the shell command by
  the same name). The interaction of this function with SIGALRM and other
  timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
  unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
		usleep(16000);
data/radeontop-1.2/include/gettext.h:189:24:  [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).
  size_t msgctxt_len = strlen (msgctxt) + 1;
data/radeontop-1.2/include/gettext.h:190:22:  [1] (buffer) strlen:
