Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Directxtex desktop 2019, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact A memory overwrite bug was reported by a security researcher in the **ConvertToSinglePlane** method via the *texconv* command-line tool when given an invalid height for planar video textures such as NV12. This can be a potential security bug for any clients of the library who follow the same pattern. This issue *does not* impact use of the DDS texture loader itself, only when combined with `ConvertToSinglePlane` for converting multi-planar video formats. All other functions in the library fail immediately if given images in planar formats. ### Patches The fix to the specific area as well as general hardening can be found in [this PR](https://github.com/microsoft/DirectXTex/pull/307) and will be included in the This bug has been fixed in the January 31, 2023 or later release of DirectXTex. ### Workarounds If your code makes use of **ConvertToSinglePlane**, you can validate that the width & height alignment requirements are met for the input image before calling the function.
