Security Fixes

CVE-2012-0461, CVE-2012-0462, CVE-2012-0464
Several flaws were found in the processing of malformed content. Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird.
CVE-2012-0456, CVE-2012-0457
Two flaws were found in the way Thunderbird parsed certain Scalable Vector Graphics (SVG) image files. An HTML mail message containing a malicious SVG image file could cause an information leak, or cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird.
CVE-2012-0455
A flaw could allow malicious content to bypass intended restrictions, possibly leading to a cross-site scripting (XSS) attack if a user were tricked into dropping a "javascript:" link onto a frame.
CVE-2012-0458
It was found that the home page could be set to a "javascript:" link. If a user were tricked into setting such a home page by dragging a link to the home button, it could cause Firefox to repeatedly crash, eventually leading to arbitrary code execution with the privileges of the user running Firefox. A similar flaw was found and fixed in Thunderbird.
CVE-2012-0459
A flaw was found in the way Thunderbird parsed certain, remote content containing "cssText". Malicious, remote content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird.
CVE-2012-0460
It was found that by using the DOM fullscreen API, untrusted content could bypass the mozRequestFullscreen security protections. Malicious content could exploit this API flaw to cause user interface spoofing.
CVE-2012-0451
A flaw was found in the way Thunderbird handled content with multiple Content Security Policy (CSP) headers. This could lead to a cross-site scripting attack if used in conjunction with a website that has a header injection flaw.
Note: All issues except CVE-2012-0456 and CVE-2012-0457 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 contains Thunderbird version 10.0.3 ESR, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect.

Security Fixes

CVE-2011-3062
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-2012-0467, CVE-2012-0468, CVE-2012-0469
Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird.
CVE-2012-0470
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-2012-0472
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-2012-0478
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-2012-0471
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-2012-0473
A flaw was found in the way Thunderbird rendered certain graphics using WebGL. Malicious content could cause Thunderbird to crash.
CVE-2012-0474
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-2012-0477
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-2012-0479
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-2011-3101, CVE-2012-1937, CVE-2012-1938, CVE-2012-1939, CVE-2012-1940, CVE-2012-1941, CVE-2012-1946, CVE-2012-1947
Several flaws were found in the processing of malformed content. Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird.
CVE-2012-1944
Note: CVE-2011-3101 only affected users of certain NVIDIA display drivers with graphics cards that have hardware acceleration enabled.
It was found that the Content Security Policy (CSP) implementation in Thunderbird no longer blocked Thunderbird inline event handlers. Malicious content could possibly bypass intended restrictions if that content relied on CSP to protect against flaws such as cross-site scripting (XSS).
CVE-2012-1945
If a web server hosted content that is stored on a Microsoft Windows share, or a Samba share, loading such content with Thunderbird could result in Windows shortcut files (.lnk) in the same share also being loaded. An attacker could use this flaw to view the contents of local files and directories on the victim's system. This issue also affected users opening content from Microsoft Windows shares, or Samba shares, that are mounted on their systems.

Bug Fix

BZ#838879
The nss update RHBA-2012:0337 for Red Hat Enterprise Linux 5 and 6 introduced a mitigation for the CVE-2011-3389 flaw. For compatibility reasons, it remains disabled by default in the nss packages. This update makes Thunderbird enable the mitigation by default. It can be disabled by setting the NSS_SSL_CBC_RANDOM_IV environment variable to 0 before launching Thunderbird.
