==========================================================================
Ubuntu Security Notice USN-2119-1
February 19, 2014

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

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

- Ubuntu 13.10
- 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:

Christian Holler, Terrence Cole, Jesse Ruderman, Gary Kwong, Eric
Rescorla, Jonathan Kew, Dan Gohman, Ryan VanderMeulen and Sotaro Ikeda
discovered multiple memory safety issues in Thunderbird. If a user were
tricked in to opening a specially crafted message with 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-2014-1477)

Cody Crews discovered a method to bypass System Only Wrappers. If a user
had enabled scripting, an attacker could potentially exploit this to steal
confidential data or execute code with the privileges of the user invoking
Thunderbird. (CVE-2014-1479)

Fredrik Lönnqvist discovered a use-after-free in Thunderbird. If a user
had enabled scripting, an attacker could potentially exploit this to cause
a denial of service via application crash, or execute arbitrary code with
the priviliges of the user invoking Thunderbird. (CVE-2014-1482)

Arthur Gerkis discovered a use-after-free in Thunderbird. If a user had
enabled scripting, an attacker could potentially exploit this to cause a
denial of service via application crash, or execute arbitrary code with
the priviliges of the user invoking Thunderbird. (CVE-2014-1486)

Masato Kinugawa discovered a cross-origin information leak in web worker
error messages. If a user had enabled scripting, an attacker could
potentially exploit this to steal confidential information.
(CVE-2014-1487)

Several issues were discovered with ticket handling in NSS. An attacker
could potentially exploit these to cause a denial of service or bypass
cryptographic protection mechanisms. (CVE-2014-1490, CVE-2014-1491)

Boris Zbarsky discovered that security restrictions on window objects
could be bypassed under certain circumstances. (CVE-2014-1481)

Fabián Cuchietti and Ateeq ur Rehman Khan discovered that it was possible
to bypass Javascript execution restrictions when replying to or forwarding
mail messages in certain circumstances. An attacker could potentially
exploit this to steal confidential information or modify message content.
(CVE-2013-6674)

Update instructions:

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

Ubuntu 13.10:
  thunderbird                     1:24.3.0+build2-0ubuntu0.13.10.1

Ubuntu 12.10:
  thunderbird                     1:24.3.0+build2-0ubuntu0.12.10.1

Ubuntu 12.04 LTS:
  thunderbird                     1:24.3.0+build2-0ubuntu0.12.04.1

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