# Qt3D: assimp scene import plugin out-of-bounds write from crafted model files

The assimp scene import plugin in the Qt3D module of the Qt Framework contains an out-of-bounds write. Per the NVD entry, a crafted scene file can corrupt memory in an application that imports 3D models through this plugin.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether your application uses the Qt3D module with the assimp scene import plugin enabled.
- Check your Qt version, for example with `qmake --version` or the Qt version your build reports; the sources do not list affected version ranges.
