Technical details

An integer overflow in the DDS RGB888 loader component of AMD Compressonator SDK results in an undersized heap allocation. When a specially crafted DDS file is processed, this leads to an out-of-bounds read on the heap, potentially causing process termination or disclosure of sensitive heap memory contents. The vulnerability requires the user to open a malicious DDS file.
