FINAL RESULTS:

data/vbetool-1.1/include/regs.h:282:5:  [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                        decode_buf[32]; /* encoded byte stream  */

  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.

data/vbetool-1.1/vbetool.c:95:23:  [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).
			return do_set_mode(atoi(argv[3]),0);
data/vbetool-1.1/vbetool.c:103:23:  [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/vbetool-1.1/vbetool.c:105:23:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range

  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
			return do_set_mode(atoi(argv[2]),1);
data/vbetool-1.1/vbetool.c:118:16:  [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).

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

  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 tmpbuffer[524288];
data/vbetool-1.1/vbetool.c:294:2:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.

data/vbetool-1.1/vbetool.c:518:3:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential

  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).

data/vbetool-1.1/x86-common.c:215:11:  [2] (misc) open:
  Check when opening files - can an attacker redirect it (via symlinks),

  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
