Debian Security Advisory

DLA-475-1 python-tornado -- LTS security update

Date Reported:
15 May 2016
Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2014-9720.
More information:

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.
