For Debian 7 'Wheezy', this issue has been fixed in gunicorn version
0.14.5-3+deb7u2.

We recommend that you upgrade your gunicorn packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
