FINAL RESULTS:

data/loadwatch-1.0+1.1alpha1/loadwatch.c:167:17:  [4] (shell) execvp:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
            if (execvp(*argv, argv) < 0)
data/loadwatch-1.0+1.1alpha1/loadwatch.c:209:9:  [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(addr.sun_path, sockname);
data/loadwatch-1.0+1.1alpha1/loadwatch.c:271:13:  [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(sockname, optarg);
data/loadwatch-1.0+1.1alpha1/loadwatch.c:506:12:  [4] (shell) popen:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
    file = popen("uptime", "r");
data/loadwatch-1.0+1.1alpha1/lw-ctl.c:23:5:  [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(addr.sun_path, sockname);
data/loadwatch-1.0+1.1alpha1/loadwatch.c:256:17:  [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 ((c = getopt(argc, argv, "d:l:h:p:u:n:")) != -1)
data/loadwatch-1.0+1.1alpha1/loadwatch.c:31:1:  [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            sockname[UNIX_PATH_MAX];
data/loadwatch-1.0+1.1alpha1/loadwatch.c:261:22:  [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).
            copies = atoi(optarg);
data/loadwatch-1.0+1.1alpha1/loadwatch.c:275:21:  [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).
            delay = atoi(optarg);
data/loadwatch-1.0+1.1alpha1/loadwatch.c:287:30:  [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).

data/loadwatch-1.0+1.1alpha1/loadwatch.c:451:5:  [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        line[81];
data/loadwatch-1.0+1.1alpha1/loadwatch.c:453:12:  [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).
    file = fopen("/proc/loadavg", "r");
data/loadwatch-1.0+1.1alpha1/loadwatch.c:504:5:  [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        line[81], *p;
data/loadwatch-1.0+1.1alpha1/loadwatch.c:97:23:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
            if ((br = read(sock, cmd + tbr, size - tbr)) < 0)
data/loadwatch-1.0+1.1alpha1/loadwatch.c:265:17:  [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).
            if (strlen(optarg) >= UNIX_PATH_MAX)
data/loadwatch-1.0+1.1alpha1/lw-ctl.c:31:13:  [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).
    total = strlen(cmd);
