Description:   A vulnerability was 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 spoof certain web sites. A remote user can obtain potentially sensitive information.

A remote user can create a specially crafted file that, when loaded by the target user, will trigger a memory corruption, use-after-free, invalid free error, memory read error, or image rendering flaw and execute arbitrary code on the target system [CVE-2012-0467, CVE-2012-0468, CVE-2012-0469, CVE-2012-0470, CVE-2012-0472, CVE-2012-0473, CVE-2012-0478]. The code will run with the privileges of the target user.

A multi-octet encoding issue may destroy following octets in the processing of some multibyte character sets [CVE-2012-0471]. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from a target site and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the 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 cause a page to load but display a different address in the address bar and then execute arbitrary scripting code in the context of the target site [CVE-2012-0474].

The software does not properly decode ISO-2022-KR and ISO-2022-CN character sets and may allow cross-site scripting attacks [CVE-2012-0477].

A remote user, when using IPv6, can cause the browser to send ambiguous origin headers in certain cases and bypass origin access controls [CVE-2012-0475].

A remote user can trigger a javascript error handling flaw to obtain the file names and location of javascript files on a target server [CVE-2011-1187].

A remote user can spoof the identity of a target secure web server hosting Atom/RSS content [CVE-2012-0479].

Bob Clary, Christian Holler, Brian Hackett, Bobby Holley, Gary Kwong, Hilary Hall, Honza Bambas, Jesse Ruderman, Julian Seward, Olli Pettay, Aki Helin, Atte Kettunen, Anne van Kesteren of Opera Software, wushi of team509 (via iDefense), Matias Juntunen, Jordi Chancel, Eddy Bordi, Chris McGowen, Simone Fabiano, Masato Kinugawa, Ms2ger, Daniel Divricean, and Jeroen van der Gun 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 a target 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 spoof certain web sites.

A remote user can obtain potentially sensitive information.

Solution:   Red Hat has issued a fix for CVE-2011-3062, CVE-2012-0467, CVE-2012-0468, CVE-2012-0469, CVE-2012-0470, CVE-2012-0471, CVE-2012-0473, CVE-2012-0474, CVE-2012-0477, CVE-2012-0478, and CVE-2012-0479. .

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.

3. Description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

A flaw was found in Sanitiser for OpenType (OTS), used by Thunderbird to
help prevent potential exploits in malformed OpenType fonts. Malicious
content could cause Thunderbird to crash or, under certain conditions,
possibly execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2011-3062)

Malicious content could cause Thunderbird to crash or, potentially, execute
arbitrary code with the privileges of the user running Thunderbird.
(CVE-2012-0467, CVE-2012-0468, CVE-2012-0469)

Content containing a malicious Scalable Vector Graphics (SVG) image file
could cause Thunderbird to crash or, potentially, execute arbitrary code
with the privileges of the user running Thunderbird. (CVE-2012-0470)

A flaw was found in the way Thunderbird used its embedded Cairo library to
render certain fonts. Malicious content could cause Thunderbird to crash
or, under certain conditions, possibly execute arbitrary code with the
privileges of the user running Thunderbird. (CVE-2012-0472)

A flaw was found in the way Thunderbird rendered certain images using
WebGL. Malicious content could cause Thunderbird to crash or, under certain
conditions, possibly execute arbitrary code with the privileges of the user
running Thunderbird. (CVE-2012-0478)

A cross-site scripting (XSS) flaw was found in the way Thunderbird handled
certain multibyte character sets. Malicious content could cause Thunderbird
to run JavaScript code with the permissions of different content.
(CVE-2012-0471)

A flaw was found in the way Thunderbird rendered certain graphics using
WebGL. Malicious content could cause Thunderbird to crash. (CVE-2012-0473)

A flaw in the built-in feed reader in Thunderbird allowed the Website field
to display the address of different content than the content the user was
visiting. An attacker could use this flaw to conceal a malicious URL,
possibly tricking a user into believing they are viewing a trusted site, or
allowing scripts to be loaded from the attacker's site, possibly leading to
cross-site scripting (XSS) attacks. (CVE-2012-0474)

A flaw was found in the way Thunderbird decoded the ISO-2022-KR and
ISO-2022-CN character sets. Malicious content could cause Thunderbird
to run JavaScript code with the permissions of different content.
(CVE-2012-0477)

A flaw was found in the way the built-in feed reader in Thunderbird handled
RSS and Atom feeds. Invalid RSS or Atom content loaded over HTTPS caused
Thunderbird to display the address of said content, but not the content.
The previous content continued to be displayed. An attacker could use this
flaw to perform phishing attacks, or trick users into thinking they are
visiting the site reported by the Website field, when the page is actually
content controlled by an attacker. (CVE-2012-0479)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Mateusz Jurczyk of the Google Security Team as the
original reporter of CVE-2011-3062; Aki Helin from OUSPG as the original
reporter of CVE-2012-0469; Atte Kettunen from OUSPG as the original
reporter of CVE-2012-0470; wushi of team509 via iDefense as the original
reporter of CVE-2012-0472; Ms2ger as the original reporter of
CVE-2012-0478; Anne van Kesteren of Opera Software as the original reporter
of CVE-2012-0471; Matias Juntunen as the original reporter of
CVE-2012-0473; Jordi Chancel and Eddy Bordi, and Chris McGowen as the
original reporters of CVE-2012-0474; Masato Kinugawa as the original
reporter of CVE-2012-0477; and Jeroen van der Gun as the original reporter
of CVE-2012-0479.

Note: All issues except CVE-2012-0470, CVE-2012-0472, and CVE-2011-3062
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.

4. Solution:

All Thunderbird users should upgrade to this updated package, which
contains Thunderbird version 10.0.4 ESR, which corrects these issues.
After installing the update, Thunderbird must be restarted for the
changes to take effect.

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/knowledge/articles/11258
