How to fix?

Upgrade Debian:10 djvulibre to version 3.5.27.1-10+deb10u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream djvulibre package and not the djvulibre package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

DjVuLibre 3.5.27 allows attackers to cause a denial-of-service attack (application crash via an out-of-bounds read) by crafting a corrupted JB2 image file that is mishandled in JB2Dict::JB2Codec::get_direct_context in libdjvu/JB2Image.h because of a missing zero-bytes check in libdjvu/GBitmap.h.
