How to fix?

Upgrade Debian:11 openjpeg2 to version 2.4.0-1 or higher.

NVD Description

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

OpenJPEG through 2.3.1 has a heap-based buffer overflow in opj_t1_clbl_decode_processor in openjp2/t1.c because of lack of opj_j2k_update_image_dimensions validation.
