# AMD Compressonator SDK: crafted DDS file can crash process or leak heap memory

AMD Compressonator SDK's DDS RGB888 loader has an integer overflow that allocates too little heap memory when given a crafted DDS file. The resulting out-of-bounds read can terminate the process or disclose limited heap memory.

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

## How to check

- Check whether your application links the Compressonator SDK and loads DDS files with it; the sources do not name affected versions, so `unknown` for version ranges
- Confirm whether untrusted users can supply DDS files to the loader

## From the sources

An integer overflow in the DDS RGB888 loader of AMD Compressonator SDK could allow an attacker to supply a crafted DDS file that causes an undersized heap allocation and a subsequent out-of-bounds read, potentially resulting in process termination or limited disclosure of heap memory.
