Later releases are readily available for the official Debian repo at Docker Hub.
Please be aware of that Etch to Squeeze images represent legacy versions of said operating system, and do contain security issues. Please do not use these images for anything else than O/S research, testing etc.
Please be aware of that since Wheezy images, images, although legacy, it still has extended security support through Freexian's ExLTS service, on specific (mostly server oriented) packages, for more information check the page at oficial Debian Extended Long Term Support wiki page.
