Ubuntu 16.04 libapache2-mod-shib2 package outdated

[Toni Sissala]

Hello list,

I have installed Shibboleth SP module for Apache via apt-get install 
libapache2-mod-shib2 on Ubuntu 16.04. This command installs Shibboleth 
Service Provider 2.5.3. but it is no longer a secure version of the 
Service Provider 
(https://wiki.shibboleth.net/confluence/display/SHIB2/Home).

There is a bug description in launchpad regarding the issue 
https://bugs.launchpad.net/ubuntu/+source/shibboleth-sp2/+bug/1636590

Is this package going to be updated? The current version is available 
for zesty and artful. I had assumed that with an LTS version, there 
should at least be backports of important packages available.


Best regards.
