Fedora 24 : python-tornado (2016-a3618d9ef6)

high Nessus Plugin ID 95731

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

Update to 4.4.2

Security fixes

 - A difference in cookie parsing between Tornado and web browsers (especially when combined with Google Analytics) could allow an attacker to set arbitrary cookies and bypass XSRF protection. The cookie parser has been rewritten to fix this attack.

Backwards-compatibility notes

 - Cookies containing certain special characters (in particular semicolon and square brackets) are now parsed differently.

 - If the cookie header contains a combination of valid and invalid cookies, the valid ones will be returned (older versions of Tornado would reject the entire header for a single invalid cookie).

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

Solution

Update the affected python-tornado package.
