thunderbird vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

Multiple security issues were fixed in Thunderbird.

Software Description:
- thunderbird: Mozilla Open Source mail and newsgroup client

Details:

Gary Kwong, Jesse Ruderman, Christian Holler, Bob Clary, Kyle Huey, Ed
Morley, Chris Lord, Boris Zbarsky, Julian Seward, Bill McCloskey, and
Andrew McCreight discovered several memory corruption flaws in Thunderbird.
If a user were tricked into opening a malicious website and had JavaScript
enabled, an attacker could exploit these to execute arbitrary JavaScript
code within the context of another website or arbitrary code as the user
invoking the program. (CVE-2012-5842, CVE-2012-5843)

Atte Kettunen discovered a buffer overflow while rendering GIF format
images. An attacker could exploit this to possibly execute arbitrary code
as the user invoking Thunderbird. (CVE-2012-4202)

It was discovered that the evalInSandbox function's JavaScript sandbox
context could be circumvented. An attacker could exploit this to perform a
cross-site scripting (XSS) attack or steal a copy of a local file if the
user has installed an add-on vulnerable to this attack. With cross-site
scripting vulnerabilities, if a user were tricked into viewing a specially
crafted page and had JavaScript enabled, a remote attacker could exploit
this to modify the contents, or steal confidential data, within the same
domain. (CVE-2012-4201)

Jonathan Stephens discovered that combining vectors involving the setting
of Cascading Style Sheets (CSS) properties in conjunction with SVG text
could cause Thunderbird to crash. If a user were tricked into opening a
malicious E-Mail, an attacker could cause a denial of service via
application crash or execute arbitrary code with the privliges of the user
invoking the program. (CVE-2012-5836)

Scott Bell discovered a memory corruption issue in the JavaScript engine.
If a user were tricked into opening a malicious website and had JavaScript
enabled, an attacker could exploit this to execute arbitrary JavaScript
code within the context of another website or arbitrary code as the user
invoking the program. (CVE-2012-4204)

Gabor Krizsanits discovered that XMLHttpRequest objects created within
sandboxes have the system principal instead of the sandbox principal. This
can lead to cross-site request forgery (CSRF) or information theft via an
add-on running untrusted code in a sandbox. (CVE-2012-4205)

Peter Van der Beken discovered XrayWrapper implementation in Firefox does
not consider the compartment during property filtering. If JavaScript were
enabled, an attacker could use this to bypass intended chrome-only
restrictions on reading DOM object properties via a crafted web site.
(CVE-2012-4208)

Bobby Holley discovered that cross-origin wrappers were allowing write
actions on objects when only read actions should have been properly
allowed. This can lead to cross-site scripting (XSS) attacks. With
cross-site scripting vulnerabilities, if a user were tricked into viewing a
specially crafted page and had JavaScript enabled, a remote attacker could
exploit this to modify the contents, or steal confidential data, within
the same domain. (CVE-2012-5841)

Masato Kinugawa discovered that when HZ-GB-2312 charset encoding is used
for text, the "~" character will destroy another character near the chunk
delimiter. This can lead to a cross-site scripting (XSS) attack in pages
encoded in HZ-GB-2312. With cross-site scripting vulnerabilities, if a user
were tricked into viewing a specially crafted page and had JavaScript
enabled, a remote attacker could exploit these to modify the contents, or
steal confidential data, within the same domain. (CVE-2012-4207)

Mariusz Mlynski discovered that the location property can be accessed by
binary plugins through top.location with a frame whose name attribute's
value is set to "top". This can allow for possible cross-site scripting
(XSS) attacks through plugins. With cross-site scripting vulnerabilities,
if a user were tricked into viewing a specially crafted page and had
JavaScript enabled, a remote attacker could exploit this to modify the
contents, or steal confidential data, within the same domain.
(CVE-2012-4209)

Abhishek Arya discovered multiple use-after-free and buffer overflow issues
in Thunderbird. If a user were tricked into opening a malicious website and
had JavaScript enabled, an attacker could exploit these to execute
arbitrary JavaScript code within the context of another website or
arbitrary code as the user invoking the program. (CVE-2012-4214,
CVE-2012-4215, CVE-2012-4216, CVE-2012-5829, CVE-2012-5839, CVE-2012-5840,
CVE-2012-4212, CVE-2012-4213, CVE-2012-4217, CVE-2012-4218)

Several memory corruption flaws were discovered in Thunderbird. If a user
were tricked into opening a malicious website and had JavaScript enabled,
an attacker could exploit these to execute arbitrary JavaScript code within
the context of another website or arbitrary code as the user invoking the
program. (CVE-2012-5830, CVE-2012-5833, CVE-2012-5835, CVE-2012-5838)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.10:
thunderbird 17.0+build2-0ubuntu0.12.10.1

Ubuntu 12.04 LTS:
thunderbird 17.0+build2-0ubuntu0.12.04.1

Ubuntu 11.10:
thunderbird 17.0+build2-0ubuntu0.11.10.1

Ubuntu 10.04 LTS:
thunderbird 17.0+build2-0ubuntu0.10.04.1

After a standard system update you need to restart Thunderbird to make all
the necessary changes.

It was discovered that if a javascript: URL is selected from the list of
Firefox "new tab" page, the script will inherit the privileges of the
privileged "new tab" page. This allows for the execution of locally
installed programs if a user can be convinced to save a bookmark of a
malicious javascript: URL. (CVE-2012-4203)

arbitrary code with the privliges of the user invoking the program.
