Examining data/erlang-p1-yaml-1.0.27/c_src/fast_yaml.c

FINAL RESULTS:

data/erlang-p1-yaml-1.0.27/c_src/fast_yaml.c:61:14:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
    if (str) memcpy(b.data, str, size);
data/erlang-p1-yaml-1.0.27/c_src/fast_yaml.c:83:13:  [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(buf, value, size);
data/erlang-p1-yaml-1.0.27/c_src/fast_yaml.c:70:21:  [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).
    if (str) size = strlen((char *) str);
