"It was discovered that python-tornado, a Python web framework and
asynchronous networking library, was susceptible for the BREACH
attack. The XSRF token is now encoded with a random mask on each
request. This makes it safe to include in compressed pages without
being vulnerable.

For Debian 7 'Wheezy', these problems have been fixed in version
2.3-2+deb7u1.

We recommend that you upgrade your python-tornado packages.

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."
