FINAL RESULTS:

data/r-cran-freetypeharfbuzz-0.2.5+dfsg/src/harfbuzz.c:45:38:  [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).
  hb_buffer_add_utf8(buffer, string, strlen(string), 0, strlen(string));
