What the vulnerability does

01Description

PHPOffice Math is a library that provides a set of classes to manipulate different formula file formats. Prior to version 0.3.0, loading XML data using the standard `libxml` extension and the `LIBXML_DTDLOAD` flag without additional filtration, leads to XXE. Version 0.3.0 fixes the vulnerability.
