FINAL RESULTS:

data/myrescue-0.9.8/src/myrescue.c:598:3:  [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 ( bitmap_name, dst_name ) ;
data/myrescue-0.9.8/src/myrescue.c:599:3:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
		strcat ( bitmap_name, bitmap_suffix ) ;
data/myrescue-0.9.8/src/myrescue.c:376:2:  [3] (random) srandom:
  This function is not sufficiently random for security-related functions
  such as key and nonce creation (CWE-327). Use a more secure technique for
  acquiring random values.
	srandom(getpid() ^ time(NULL));
data/myrescue-0.9.8/src/myrescue.c:480:25:  [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.

data/myrescue-0.9.8/src/myrescue-bitmap2ppm.c:71:7:  [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).
		w = atoi(argv[arg]);
data/myrescue-0.9.8/src/myrescue-bitmap2ppm.c:76:8:  [2] (integer) atoi:

  input had no minus sign (large numbers can roll over into negative number;

data/myrescue-0.9.8/src/myrescue-stat.c:38:11:  [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.
	unsigned char buffer[BUFFER_SIZE];
data/myrescue-0.9.8/src/myrescue.c:56:7:  [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).
