Fedora 21 : python-tornado-3.2.2-1.fc21 (2015-8606)

medium Nessus Plugin ID 84096

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

Security fixes

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. This applies to most applications that use both the xsrf_cookies and gzip options (or have gzip applied by a proxy).

Backwards-compatibility notes

If Tornado 3.2.2 is run at the same time as older versions on the same domain, there is some potential for issues with the differing cookie versions. The Application setting xsrf_cookie_version=1 can be used for a transitional period to generate the older cookie format on newer servers.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-tornado package.
