Security fix for CVE-2021-3630

Summary

DjVu is a web-centric format and software platform for distributing documents

and images. DjVu can advantageously replace PDF, PS, TIFF, JPEG, and GIF for

distributing scanned documents, digital documents, or high-resolution pictures.

DjVu content downloads faster, displays and renders faster, looks nicer on a

screen, and consume less client resources than competing formats. DjVu images

display instantly and can be smoothly zoomed and panned with no lengthy

re-rendering.

DjVuLibre is a free (GPL'ed) implementation of DjVu, including viewers,

decoders, simple encoders, and utilities. The browser plugin is in its own

separate sub-package.
