Debian DLA-279-1 : python-tornado security update

medium Nessus Plugin ID 84932

Language:

Synopsis

The remote Debian host is missing a security update.

Description

A vulnerability was discovered in python-tornado, a Python scalable, non- blocking web server.

CVE-2014-9720

CSRF cookie allows side-channel attack against TLS (BREACH)

Security Fix

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 to the BREACH attack. For the oldoldstable distribution (squeeze), this problem has been fixed in version 1.0.1-1+deb6u1.

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.

Solution

Upgrade the affected python-tornado package.
