TL;DR

OpenEXRCore's NO_COMPRESSION scanline path accepts a chunk shorter than the declared unpacked pixel data. The short chunk leaves part of the destination buffer uninitialized, and those bytes can be copied into caller-visible pixels during decode. The fix rejects undersized compressed or raw streams before reconstructing full channel rows.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and you decode untrusted uncompressed scanline EXR files.

Background info

AcademySoftwareFoundation.openexr is vulnerable to Information Disclosure in versions 3.1.0 - 3.4.13.

How to fix this

Upgrade the AcademySoftwareFoundation.openexr library to the patch version.
