There is a difference here, apt shows 1.0.1t-1+deb8u6 as most recent
version (which is the most recent version on my Jessie install too, so
that's fine), but `openssl version` shows a different version (1.0.2
instead of 1.0.1). Did you install openssl from source as well? I
wouldn't be surprised if `which openssl` showed something other than
/usr/bin/openssl which is where the packages are installed.

If you're actually using the Debian-packages for OpenSSL, there is not
much added value by letting freeradius check for vulnerabilities. Mostly
OpenSSL of Debian is patched faster than you'd upgrade your RADIUS
server, and because fixes are backported the version check doesn't make
much sense either. You could pass --disable-openssl-version-check to the
build to disable openssl version checks, or build the Debian packages
( which include
this switch by default.
