(Red Hat Issues Fix) Mozilla Thunderbird Multiple Flaws Permit Remote Code Execution, Information Disclosure, and Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1026619
SecurityTracker URL:  http://securitytracker.com/id/1026619
CVE Reference:   CVE-2012-0442   (Links to External Site)
Date:  Feb 1 2012
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 3.1.18, prior to 10.0
Description:   Multiple vulnerabilities were reported in Mozilla Thunderbird. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can conduct cross-site scripting attacks. A remote user can obtain cross-domain information.

A remote user can create a specially crafted content that, when loaded by the target user, will trigger a memory corruption error and execute arbitrary code on the target user's system [CVE-2012-0442, CVE-2012-0443]. The code will run with the privileges of the target user.

A remote user can bypass HTML5 frame navigation controls, replacing a sub-frame in a target domain's document by using the name attribute of the sub-frame as a form submission target [CVE-2012-0445]. Version 3.6 is not affected.

In certain situations, a removed child node of nsDOMAttribute can be accessed [CVE-2011-3659].

Frame scripts can bypass XPConnect security checks when calling untrusted objects, allowing a remote user to conduct cross-site scripting attacks via web pages and Firefox extensions [CVE-2012-0446].

The 'image/vnd.microsoft.icon' output may include uninitialized memory [CVE-2012-0447]. A remote user may be able to access potentially sensitive data, such as when a PNG image is converted from an ICO format. Version 3.6 is not affected.

A remote user can create a specially crafted Ogg Vorbis file that, when loaded by the target user, will trigger a memory corruption error and potentially execute arbitrary code on the target user's system [CVE-2012-0444].

A remote user can create a specially crafted embedded XSLT stylesheet that, when loaded by the target user, will trigger a memory corruption error and potentially execute arbitrary code on the target user's system [CVE-2012-0449].

Ben Hawkes, Christian Holler, Honza Bombas, Jason Orendorff, Jesse Ruderman, Jan Odvarko, Peter Van Der Beken, Bill McCloskey, Bob Clary, Alex Dvorov, regenrecht (via TippingPoint's Zero Day Initiative), moz_bug_r_a4, Tim Abraldes, Nicolas Gregoire, and Aki Helin reported these vulnerabilities.
Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with an arbitrary site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote user can obtain potentially sensitive information from other domains.
Solution:   Red Hat has issued a fix for CVE-2012-0442.

=====================================================================
                   Red Hat Security Advisory

Synopsis:          Critical: thunderbird security update
Advisory ID:       RHSA-2012:0085-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2012-0085.html
Issue date:        2012-02-01
CVE Names:         CVE-2011-3670 CVE-2012-0442 
=====================================================================

1. Summary:

An updated thunderbird package that fixes two security issues is now
available for Red Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having critical
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

RHEL Optional Productivity Applications (v. 5 server) - i386, x86_64
Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

A flaw was found in the processing of malformed content. An HTML mail
message containing malicious content could cause Thunderbird to crash or,
potentially, execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2012-0442)

The same-origin policy in Thunderbird treated http://example.com and
http://[example.com] as interchangeable. A malicious script could possibly
use this flaw to gain access to sensitive information (such as a client's
IP and user e-mail address, or httpOnly cookies) that may be included in
HTTP proxy error replies, generated in response to invalid URLs using
square brackets. (CVE-2011-3670)

Note: The CVE-2011-3670 issue cannot be exploited by a specially-crafted
HTML mail message as JavaScript is disabled by default for mail messages.
It could be exploited another way in Thunderbird, for example, when viewing
the full remote content of an RSS feed.

All Thunderbird users should upgrade to this updated package, which
resolves these issues. All running instances of Thunderbird must be
restarted for the update to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259
