From 3.4.0 to before 3.4.9, a missing bounds check on the dataWindow attribute in EXR file headers allows an attacker to trigger a signed integer overflow in generic_unpack(). By setting dataWindow.min.x to a large negative value, OpenEXRCore computes an enormous image width, which is later used in a signed integer multiplication that overflows, causing the process to terminate with SIGILL via UBSan. This vulnerability is fixed in 3.4.9.</p> <p><strong>Affected:</strong> AcademySoftwareFoundation openexr</p> <p>OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry.
