FINAL RESULTS:

data/daa2iso-0.1.7e/src/daa2iso.c:759:5:  [4] (format) sprintf:
  Potential format string problem (CWE-134). Make format string constant.
    sprintf(toadd, fmt, multinum);
data/daa2iso-0.1.7e/src/LzmaDec.c:789:13:  [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(p->tempBuf, src, inSize);
data/daa2iso-0.1.7e/src/LzmaDec.c:877:5:  [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(dest, p->dic + dicPos, outSizeCur);
data/daa2iso-0.1.7e/src/daa2iso.c:71:17:  [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).
        #define fopen   fopen64
data/daa2iso-0.1.7e/src/daa2iso.c:210:43:  [2] (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). Risk is low because the
  source is a constant string.

  maximum possible length.
