"It is not feasible to fully support some Debian packages through the
releases life cycle. The debian-security-support package provides the
check-support-status tool that helps to warn the administrator about
installed packages whose security support is limited or has to
prematurely end.

For Debian 7 'Wheezy', debian-security-support version
2016.05.09+nmu1~deb7u1 updates the list of packages with restricted
support in Wheezy LTS. In particular, this version also includes a new
feature to notify the user about oncoming end-of-lifes.

We recommend you to install the debian-security-support and run
check-support-status to verify the status of installed packages.
Please, refer to the check-support-status (1) man page for more
information about how to use it.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
