Ubuntu Several security issues were fixed in Thunderbird.
==========================================================================
Ubuntu Security Notice USN-1748-1
February 25, 2013

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:

Several security issues were fixed in Thunderbird.

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

Details:

Bobby Holley discovered vulnerabilities in Chrome Object Wrappers (COW) and
System Only Wrappers (SOW). If a user were tricked into opening a specially
crafted page and had scripting enabled, a remote attacker could exploit
this to bypass security protections to obtain sensitive information or
potentially execute code with the privileges of the user invoking
Thunderbird. (CVE-2013-0773)

Frederik Braun discovered that Thunderbird made the location of the active
browser profile available to JavaScript workers. Scripting for Thunderbird
is disabled by default in Ubuntu. (CVE-2013-0774)

A use-after-free vulnerability was discovered in Thunderbird. An attacker
could potentially exploit this to execute code with the privileges of the
user invoking Thunderbird if scripting were enabled. (CVE-2013-0775)

Michal Zalewski discovered that Thunderbird would not always show the
correct address when cancelling a proxy authentication prompt. A remote
attacker could exploit this to conduct URL spoofing and phishing attacks
if scripting were enabled.
(CVE-2013-0776)

Abhishek Arya discovered several problems related to memory handling. 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-2013-0777, CVE-2013-0778, CVE-2013-0779, CVE-2013-0780,
CVE-2013-0781, CVE-2013-0782)

Olli Pettay, Christoph Diehl, Gary Kwong, Jesse Ruderman, Andrew McCreight,
Joe Drew, Wayne Mery, Alon Zakai, Christian Holler, Gary Kwong, Luke
Wagner, Terrence Cole, Timothy Nikkel, Bill McCloskey, and Nicolas Pierron
discovered multiple memory safety issues affecting Thunderbird. If a user
had scripting enabled and was tricked into opening a specially crafted
page, an attacker could possibly exploit these to cause a denial of service
via application crash. (CVE-2013-0783, CVE-2013-0784)

Update instructions:

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

Ubuntu 12.10:
  thunderbird                     17.0.3+build1-0ubuntu0.12.10.1

Ubuntu 12.04 LTS:
  thunderbird                     17.0.3+build1-0ubuntu0.12.04.1

Ubuntu 11.10:
  thunderbird                     17.0.3+build1-0ubuntu0.11.10.1

Ubuntu 10.04 LTS:
  thunderbird                     17.0.3+build1-0ubuntu0.10.04.1

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