FINAL RESULTS:

data/fscrypt-0.2.9/pam/pam.c:98:3:  [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(copy, data, size);
data/fscrypt-0.2.9/pam/pam.c:95:17:  [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).
  size_t size = strlen(data) + 1;  // include null terminator
data/fscrypt-0.2.9/pam/pam.c:103:17:  [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).
  size_t size = strlen(data) + 1;  // Include null terminator
