TL;DR

OpenEXRCore's exr_set_channels() and exr_attr_set_channels() validate the top-level channel-list pointer but not a NULL nested entries pointer when num_channels is nonzero. The code then performs pointer arithmetic on entries and dereferences it, crashing the process. This is reachable through the public OpenEXRCore C API rather than by opening a crafted EXR alone. The fix rejects num_channels greater than zero with entries equal to NULL before any entry access.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and you call exr_set_channels() or exr_attr_set_channels() with untrusted or insufficiently validated channel-list data.

Background info

AcademySoftwareFoundation.openexr is vulnerable to NULL Pointer Dereference in versions 3.1.0 - 3.4.13.

How to fix this

Upgrade the AcademySoftwareFoundation.openexr library to the patch version.
