CVE-2026-42146 (opens in a new tab)How to fix?
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 c3aacf5, the nb_colors field read from the BMP file header is used directly to compute an allocation size without validating it against the remaining file size. A crafted BMP file with a large nb_colors value triggers an out-of-memory condition, crashing any application that uses CImg to load untrusted BMP files. This issue has been patched via commit c3aacf5.
