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

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

- Ubuntu 13.10
- 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:

Ben Turner, Bobby Holley, Jesse Ruderman and Christian Holler 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-2013-5609)

Tyson Smith and Jesse Schwartzentruber discovered a use-after-free in
event listeners. 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 privileges of the user invoking
Thunderbird. (CVE-2013-5616)

A use-after-free was discovered in the table editing interface. An
attacker could potentially exploit this to cause a denial of service via
application crash, or execute arbitrary code with the privileges of the
user invoking Thunderbird. (CVE-2013-5618)

Tyson Smith and Jesse Schwartzentruber discovered a crash when inserting
an ordered list in to a document using script. If a user had enabled
scripting, an attacker could potentially exploit this to execute
arbitrary code with the privileges of the user invoking Thunderbird.
(CVE-2013-6671)

Sijie Xia discovered that trust settings for built-in EV root certificates
were ignored under certain circumstances, removing the ability for a user
to manually untrust certificates from specific authorities.
(CVE-2013-6673)

Tyson Smith, Jesse Schwartzentruber and Atte Kettunen discovered a
use-after-free in functions for synthetic mouse movement handling. 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 privileges of the user invoking Thunderbird. (CVE-2013-5613)

Eric Faust discovered that GetElementIC typed array stubs can be generated
outside observed typesets. If a user had enabled scripting, an attacker
could possibly exploit this to cause undefined behaviour with a potential
security impact. (CVE-2013-5615)

Michal Zalewski discovered several issues with JPEG image handling. An
attacker could potentially exploit these to obtain sensitive information.
(CVE-2013-6629, CVE-2013-6630)

Update instructions:

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

Ubuntu 13.10:
  thunderbird                     1:24.2.0+build1-0ubuntu0.13.10.1

Ubuntu 13.04:
  thunderbird                     1:24.2.0+build1-0ubuntu0.13.04.1

Ubuntu 12.10:
  thunderbird                     1:24.2.0+build1-0ubuntu0.12.10.1

Ubuntu 12.04 LTS:
  thunderbird                     1:24.2.0+build1-0ubuntu0.12.04.1

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