FINAL RESULTS:

data/libimagequant-2.12.2/libimagequant.c:158:30:  [4] (format) vsnprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
        int required_space = vsnprintf(NULL, 0, fmt, va)+1; // +\0

  a constant for the format specification.
        vsnprintf(buf, required_space, fmt, va);
data/libimagequant-2.12.2/example.c:97:16:  [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 *fp = fopen(output_png_file_path, "wb");
data/libimagequant-2.12.2/libimagequant.c:660:9:  [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(tmp, importance_map, required_size);
data/libimagequant-2.12.2/libimagequant.c:796:9:  [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(temp_row, img->rows[row], img->width * sizeof(temp_row[0]));
data/libimagequant-2.12.2/pam.c:133:25:  [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(new_items, other_items, sizeof(other_items[0])*achl->capacity);
