## Description

An issue has been found in Mini-XML (aka mxml) 2.12. It is a stack-based buffer overflow in mxml_write_node in mxml-file.c via vectors involving a double-precision floating point number and the '<order type="real">' substring, as demonstrated by testmxml.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
