FINAL RESULTS:

data/xautomation-1.09/debug.h:28:58:  [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 dmsg( x, y, args... )   if( x <= _DEBUGLEVEL ) { fprintf( stderr, "DEBUG %d) " y, x, ## args ); }
data/xautomation-1.09/visgrep.c:58:20:  [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( ( opt = getopt( argc, argv, "hX:Y:x:d:y:t:baW:H:" ) ) != EOF ) {
data/xautomation-1.09/xmousepos.c:63:31:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
        if (! (display_name = getenv("DISPLAY")) ){
data/xautomation-1.09/xte.c:344:20:  [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( ( opt = getopt( argc, argv, "hd:x:i:" ) ) != EOF ) {
data/xautomation-1.09/image.c:58:5:  [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 sig[ 4 ];
data/xautomation-1.09/image.c:64:9:  [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( fname, "r" );
data/xautomation-1.09/image.c:118:9:  [2] (misc) fopen:
  Check when opening files - can an attacker redirect it (via symlinks),

  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).

  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
    FILE *in = fopen( fname, "rb" );
data/xautomation-1.09/image.c:337:9:  [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( fname, "w" );
data/xautomation-1.09/image.c:367:9:  [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( fname, "w" );
data/xautomation-1.09/xte.c:162:5:  [2] (buffer) wchar_t:
  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.
    wchar_t thing[ CMD_STRING_MAXLEN ];
data/xautomation-1.09/xte.c:163:5:  [2] (buffer) wchar_t:
  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.
    wchar_t wc_singlechar_str[2];
data/xautomation-1.09/xte.c:237:5:  [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 str[ CMD_STRING_MAXLEN ];
data/xautomation-1.09/xte.c:34:39:  [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).
#define IS_CMD( x, y ) strncmp( x, y, strlen( y ) ) == 0
data/xautomation-1.09/xte.c:246:9:  [1] (buffer) strncpy:

  pointers [MS-banned] (CWE-120).
        strncpy( str, &cmd[ 4 ], 128 );
data/xautomation-1.09/xte.c:249:9:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).

data/xautomation-1.09/xte.c:252:9:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
        strncpy( str, &cmd[ 6 ], CMD_STRING_MAXLEN );
data/xautomation-1.09/xte.c:267:9:  [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( tmpx );
data/xautomation-1.09/xte.c:277:9:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
        strncpy( str, &cmd[ 4 ], CMD_STRING_MAXLEN );
data/xautomation-1.09/xte.c:458:18:  [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).
            buf[ strlen( buf ) - 1 ] = 0; /* Chop \n */
