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 potentially sensitive information.
A remote user can create specially crafted HTML that, when loaded by the target user, will execute arbitrary code on the target user's system [CVE-2011-3651, CVE-2011-3652, CVE-2011-3654]. The code will run with the privileges of the target user. Version 7.x is affected. Jason Orendorff, Boris Zbarsky, Gregg Tavares, Mats Palmgren, Christian Holler, Jesse Ruderman, Simona Marcu, Bob Clary, William McCloskey, Rh0, and Aki Helin reported these vulnerabilities.
When using Firebug to profile a JavaScript file, a remote user may be able to execute arbitrary code [CVE-2011-3650]. Marc Schoenefeld reported this vulnerability.
A remote user can conduct cross-origin data access attacks [CVE-2011-3649]. Mozilla developer Bas Schouten reported this vulnerability. [Editor's note: This vulnerability was previously reported in MFSA 2011-29 and was reintroduced by the introduction of the "Azure" graphics back-end on Windows in Thunderbird 7.]
A remote user may be able to view random images from GPU memory in WebGL textures due to an Intel driver bug in some Mac OS X hardware [CVE-2011-3653]. Claus Wahlers reported this vulnerability.
The loadSubscript() function unwraps XPCNativeWrappers, which may allow a remote user to gain elevated privileges [CVE-2011-3647]. Only version 3.1.x is affected. moz_bug_r_a4 reported this vulnerability. [Editor's note: This vulnerability was previously reported to affect other versions of Thunderbird [in MFSA 2011-43; CVE-2011-3004; Alert ID 1026121]].
A remote user can bypass an internal NoWaiverWrappers privilege check to cause code to be executed with elevated privileges [CVE-2011-3655]. moz_bug_r_a4 reported this vulnerability.
A remote user can supply invalid sequences in the Shift-JIS encoding to conduct cross-site scripting attacks [CVE-2011-3648]. Yosuke Hasegawa reported this vulnerability.

Impact:
A remote user can create HTML that, when loaded by the target user, will execute arbitrary code on the target user's system.

3. Description:
Mozilla Thunderbird is a standalone mail and newsgroup client.
A flaw was found in the way Thunderbird handled certain add-ons. Malicious,
remote content could cause an add-on to elevate its privileges, which could
lead to arbitrary code execution with the privileges of the user running
Thunderbird. (CVE-2011-3647)
A cross-site scripting (XSS) flaw was found in the way Thunderbird handled
certain multibyte character sets. Malicious, remote content could cause
Thunderbird to run JavaScript code with the permissions of different
remote content. (CVE-2011-3648)
A flaw was found in the way Thunderbird handled large JavaScript scripts.
Malicious, remote content could cause Thunderbird to crash or, potentially,
execute arbitrary code with the privileges of the user running Thunderbird.
(CVE-2011-3650)
All Thunderbird users should upgrade to this updated package, which
resolves these issues. All running instances of Thunderbird must be
