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

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

- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

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

Details:

Multiple memory safety issues were discovered in Thunderbird. If a user
were tricked in to opening a specially crafted message with scripting
enabled, an attacker could possibly exploit these to cause a denial of
service via application crash, or potentially execute arbitrary code with
the privileges of the user invoking Thunderbird. (CVE-2013-1718)

Atte Kettunen discovered a flaw in the HTML5 Tree Builder when interacting
with template elements. If a user had scripting enabled, in some
circumstances an attacker could potentially exploit this to execute
arbitrary code with the privileges of the user invoking Thunderbird.
(CVE-2013-1720)

Alex Chapman discovered an integer overflow vulnerability in the ANGLE
library. If a user had scripting enabled, an attacker could potentially
exploit this to execute arbitrary code with the privileges of the user
invoking Thunderbird. (CVE-2013-1721)

Abhishek Arya discovered a use-after-free in the Animation Manager. If
a user had scripting enabled, an attacked could potentially exploit this
to execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2013-1722)

Scott Bell discovered a use-after-free when using a select element. If
a user had scripting enabled, an attacker could potentially exploit this
to execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2013-1724)

It was discovered that the scope of new Javascript objects could be
accessed before their compartment is initialized. If a user had scripting
enabled, an attacker could potentially exploit this to execute code with
the privileges of the user invoking Thunderbird. (CVE-2013-1725)

Dan Gohman discovered that some variables and data were used in IonMonkey,
without being initialized, which could lead to information leakage.
(CVE-2013-1728)

Sachin Shinde discovered a crash when moving some XBL-backed nodes
in to a document created by document.open(). If a user had scripting
enabled, an attacker could potentially exploit this to cause a denial
of service. (CVE-2013-1730)

Aki Helin discovered a buffer overflow when combining lists, floats and
multiple columns. If a user had scripting enabled, an attacker could
potentially exploit this to execute arbitrary code with the privileges
of the user invoking Thunderbird. (CVE-2013-1732)

Two memory corruption bugs when scrolling were discovered. If a user had
scripting enabled, an attacker could potentially exploit these to cause a
denial of service via application crash, or execute arbitrary code with
the privileges of the user invoking Thunderbird. (CVE-2013-1735,
CVE-2013-1736)

Boris Zbarsky discovered that user-defined getters on DOM proxies would
use the expando object as "this". If a user had scripting enabled, an
attacker could potentially exploit this by tricking add-on code in to
making incorrect security sensitive decisions based on malicious values.
(CVE-2013-1737)

A use-after-free bug was discovered in Thunderbird. If a user had
scripting enabled, an attacker could potentially exploit this to execute
arbitrary code with the privileges of the user invoking Thunderbird.
(CVE-2013-1738)

Update instructions:

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

Ubuntu 13.04:
  thunderbird                     1:24.0+build1-0ubuntu0.13.04.1

Ubuntu 12.10:
  thunderbird                     1:24.0+build1-0ubuntu0.12.10.1

Ubuntu 12.04 LTS:
  thunderbird                     1:24.0+build1-0ubuntu0.12.04.1

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