There is no fixed version for Debian:11 openjpeg2.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openjpeg2 package and not the openjpeg2 package as distributed by Debian:11. See How to fix? for Debian:11 relevant fixed versions and status.

A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the way it handles an input directory with a large number of files. When it fails to allocate a buffer to store the filenames of the input directory, it calls free() on an uninitialized pointer, leading to a segmentation fault and a denial of service.
