# AMD Compressonator SDK: crafted DDS file causes integer overflow and denial of service

The AMD Compressonator SDK has an integer overflow when parsing DirectDraw Surface (DDS) image files. A local attacker who supplies a specially crafted DDS file can crash the program, causing denial of service.

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

## How to check

- Check whether your code or build pipeline depends on the AMD Compressonator SDK (look for Compressonator in your dependencies or build scripts).
- Confirm the installed SDK version and compare it with the version ranges in the NVD entry; the sources do not list affected versions.

## From the sources

An integer overflow condition in the AMD Compressonator SDK could allow an attacker with local access to supply a specially crafted DirectDraw Surface (DDS) file, potentially resulting in denial of service (DoS).
