Debian Bug : #1005041

It was discovered that there was an information disclosure issue in
python-treq, a high-level library/API for making HTTP requests using
the Twisted network programming library. HTTP cookies were not bound
to a single domain and were instead sent to every domain.

For Debian 9 "Stretch", this problem has been fixed in version
15.1.0-1+deb9u1.

We recommend that you upgrade your python-treq packages.
