There is no fixed version for Debian:11 cimg.
NVD Description
Note: Versions mentioned in the description apply only to the upstream cimg package and not the cimg package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
CImg Library is a C++ library for image processing. Prior to commit 4ca26bc, there is an integer overflow vulnerability in the WHD size computation inside _load_pnm() that can bypass the memory allocation guard. A crafted PNM/PGM/PPM file with large dimension values causes the overflow to wrap around, allocating an undersized buffer and potentially triggering a heap buffer overflow. Any application using CImg to load untrusted image files is affected. This issue has been patched via commit 4ca26bc.
