Will openssl on Ubuntu 12.04 and 14.04 be maintained after Dec 31, 2016?

12.04 (EOL April 2017) and 14.04 (EOL 2019) both appear to use openssl 1.0.1, which is apparently not going to be supported at all after December 31, 2016 (according to openssl.org/source).

Will security fixes be backported into the openssl packages running on 12.04 and 14.04 for as long as those versions are supported? Or will a version upgrade (e.g., to 16.04 for LTS) be required?
