FINAL RESULTS:

data/nbibtex-0.9.18/nbib.c:579:13:  [2] (misc) fopen:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
  FILE *f = fopen(filename, "r");
data/nbibtex-0.9.18/nbib.c:435:12:  [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).
  for (n = strlen((char *)buf); buf[n-1] != '\n'; n = strlen((char *)buf)) {
data/nbibtex-0.9.18/nbib.c:435:55:  [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).
  for (n = strlen((char *)buf); buf[n-1] != '\n'; n = strlen((char *)buf)) {
data/nbibtex-0.9.18/nbib.c:441:11:  [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).
      n = strlen((char *)buf) + 1;  /* -1 below is incorrect without newline */
data/nbibtex-0.9.18/nbib.c:608:3:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
  strncpy((char *)rdr->filename, filename, lua_strlen(L, 1)+1);
