========================================
Severity: Critical
Date    : 2015-01-14
CVE-ID  : CVE-2014-8634 CVE-2014-8635 CVE-2014-8638 CVE-2014-8639
Package : thunderbird
Type    : multiple issues
Remote  : Yes
Link    : https://wiki.archlinux.org/title/CVE

Summary
======
The package thunderbird before version 31.4.0-1 is vulnerable to
multiple issues, that Mozilla believes not to be exploitable through
email. Upgrading is still advised.

Resolution
=========
Upgrade to 31.4.0-1.

# pacman -Syu "thunderbird>=31.4.0-1"

The problem has been fixed upstream in version 31.4.0.

Workaround
=========
None.

Description
==========

- CVE-2014-8634 (arbitrary remote code execution)

Christian Holler and Patrick McManus reported memory safety problems and
crashes that affect Firefox ESR 31.3 and Firefox 34.

- CVE-2014-8635 (arbitrary remote code execution)

Christoph Diehl, Christian Holler, Gary Kwong, Jesse Ruderman, Byron
Campen, Terrence Cole, and Nils Ohlmeier reported memory safety problems
and crashes that affect Firefox 34.

- CVE-2014-8638 (XSRF)

Security researcher Muneaki Nishimura reported that
navigator.sendBeacon() does not follow the cross-origin resource sharing
(CORS) specification. This results in the request from sendBeacon()
lacking an origin header in violation of the W3C Beacon specification
and not being treated as a CORS request. This allows for a potential
Cross-site request forgery (XSRF) attack from malicious websites.

- CVE-2014-8639 (cookie injection)

Security researcher Xiaofeng Zheng of the Blue Lotus Team at Tsinghua
University reported reported that a Web Proxy returning a 407 Proxy
Authentication response with a Set-Cookie header could inject cookies
into the originally requested domain. This could be used for
session-fixation attacks. This attack only allows cookies to be written
but does not allow them to be read.

Impact
=====
Mozilla believes that these issues cannot be exploited by e-mail, either
because scripting is disabled or because no HTTP request should be
initiated by thunderbird.
