The record
The spritefont reader can be induced to perform a 32-bit overflow multiply that could in theory result in a RCE. This impacts the use of the *DirectX Tool Kit* **SpriteFont** class file loading ctor if given untrusted data files. > Note this only applies to x86/ARM builds of the library. ARM64 and x64 native is not subject to this issue.
