How to fix?

Upgrade Debian:11 openexr to version 2.5.3-2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openexr package and not the openexr package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

An issue was discovered in OpenEXR before 2.4.1. Because of integer overflows in CompositeDeepScanLine::Data::handleDeepFrameBuffer and readSampleCountForLineBlock, an attacker can write to an out-of-bounds pointer.
