CVE-2025-59733
Description
A flaw was found in FFmpeg. This vulnerability allows a buffer overflow via a specially crafted OpenEXR (EXR) file using DWAA (DreamWorks Animation Adaptive) or DWAB (DreamWorks Animation B-wave) compression, due to incorrect handling of image channel pixel types during decoding.
Statement
The highest threat is to system availability, as processing a specially crafted OpenEXR file with DWAA/DWAB compression can lead to a buffer overflow in FFmpeg, resulting in a denial of service. This requires an attacker to be on the same adjacent network.
