FINAL RESULTS:

data/ruby-zoom-0.5.0/ext/rbzoomoptions.c:80:21:  [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).
    return INT2FIX (atoi (value));
data/ruby-zoom-0.5.0/ext/rbzoomoptions.c:86:5:  [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 code [1024];

data/ruby-zoom-0.5.0/ext/rbzoomoptions.c:76:21:  [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).
