FINAL RESULTS:

data/ruby-curb-0.9.10/ext/curb_easy.c:63:7:  [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(ptr, RSTRING_PTR(str), RSTRING_LEN(str));
data/ruby-curb-0.9.10/ext/curb_easy.c:84:9:  [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(ptr, str_ptr+rbcu->offset, remaining);
data/ruby-curb-0.9.10/ext/curb_easy.c:91:7:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).

  memcpy(newrbce, rbce, sizeof(ruby_curl_easy));
data/ruby-curb-0.9.10/ext/curb_easy.c:3631:3:  [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 buf[64];
data/ruby-curb-0.9.10/ext/curb_easy.c:3639:5:  [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(buf,"#<Curl::Easy ", 13);
data/ruby-curb-0.9.10/ext/curb_easy.c:3640:5:  [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(buf+13,StringValueCStr(url), (len - 13));
data/ruby-curb-0.9.10/ext/curb_easy.c:3702:10:  [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).
  rlen = strlen(result);
