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

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

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

Details:

Benoit Jacob, Jesse Ruderman, Christian Holler, Bill McCloskey, Brian Smith,
Gary Kwong, Christoph Diehl, Chris Jones, Brad Lassey, and Kyle Huey discovered
memory safety issues affecting Thunderbird. If the user were tricked into
opening a specially crafted page, an attacker could possibly exploit these to
cause a denial of service via application crash, or potentially execute code
with the privileges of the user invoking Thunderbird. (CVE-2012-1948,
CVE-2012-1949)

Abhishek Arya discovered four memory safety issues affecting Thunderbird. If
the user were tricked into opening a specially crafted page, an attacker could
possibly exploit these to cause a denial of service via application crash, or
potentially execute code with the privileges of the user invoking Thunderbird.
(CVE-2012-1951, CVE-2012-1952, CVE-2012-1953, CVE-2012-1954)

Mariusz Mlynski discovered that the address bar may be incorrectly updated.
Calls to history.forward and history.back could be used to navigate to a site
while the address bar still displayed the previous site. A remote attacker
could exploit this to conduct phishing attacks. (CVE-2012-1955)

Mario Heiderich discovered that HTML <embed> tags were not filtered out of the
HTML <description> of RSS feeds. A remote attacker could exploit this to
conduct cross-site scripting (XSS) attacks via javascript execution in the HTML
feed view. (CVE-2012-1957)

Arthur Gerkis discovered a use-after-free vulnerability. If the user were
tricked into opening a specially crafted page, an attacker could possibly
exploit this to cause a denial of service via application crash, or potentially
execute code with the privileges of the user invoking Thunderbird.
(CVE-2012-1958)

Bobby Holley discovered that same-compartment security wrappers (SCSW) could be
bypassed to allow XBL access. If the user were tricked into opening a specially
crafted page, an attacker could possibly exploit this to execute code with the
privileges of the user invoking Thunderbird. (CVE-2012-1959)

Tony Payne discovered an out-of-bounds memory read in Mozilla's color
management library (QCMS). If the user were tricked into opening a specially
crafted color profile, an attacker could possibly exploit this to cause a
denial of service via application crash. (CVE-2012-1960)

Frédéric Buclin discovered that the X-Frame-Options header was ignored when its
value was specified multiple times. An attacker could exploit this to conduct
clickjacking attacks. (CVE-2012-1961)

Bill Keese discovered a memory corruption vulnerability. If the user were
tricked into opening a specially crafted page, an attacker could possibly
exploit this to cause a denial of service via application crash, or potentially
execute code with the privileges of the user invoking Thunderbird.
(CVE-2012-1962)

Karthikeyan Bhargavan discovered an information leakage vulnerability in the
Content Security Policy (CSP) 1.0 implementation. If the user were tricked into
opening a specially crafted page, an attacker could possibly exploit this to
access a user's OAuth 2.0 access tokens and OpenID credentials. (CVE-2012-1963)

It was discovered that the execution of javascript: URLs was not properly
handled in some cases. A remote attacker could exploit this to execute code
with the privileges of the user invoking Thunderbird. (CVE-2012-1967)

Update instructions:

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

Ubuntu 12.04 LTS:
  thunderbird                     14.0+build1-0ubuntu0.12.04.1

Ubuntu 11.10:
  thunderbird                     14.0+build1-0ubuntu0.11.10.1

Ubuntu 11.04:
  thunderbird                     14.0+build1-0ubuntu0.11.04.1

Ubuntu 10.04 LTS:
  thunderbird                     14.0+build1-0ubuntu0.10.04.1

When upgrading, users should be aware of the following:

- In Ubuntu 11.04, unity-2d users may lose the ability to view drop-down menus,
context menus, and perform drag-and-drop operations in Thunderbird. This is a
known issue being tracked in https://launchpad.net/bugs/1020198 and may be
fixed in a later update.

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