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

- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

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

Details:

Gary Kwong, Christoph Diehl, Christian Holler, Hannes Verschore, Jan de
Mooij, Ryan VanderMeulen, Jeff Walden and Kyle Huey 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-2014-1533)

Abhishek Arya discovered multiple use-after-free and out-of-bounds read
issues in Thunderbird. If a user had enabled scripting, an attacker could
potentially exploit these to cause a denial of service via application
crash or execute arbitrary code with the priviliges of the user invoking
Thunderbird. (CVE-2014-1538)

A use-after-free was discovered in the SMIL animation controller. 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-2014-1541)

Update instructions:

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

Ubuntu 14.04 LTS:
  thunderbird                     1:24.6.0+build1-0ubuntu0.14.04.1

Ubuntu 12.04 LTS:
  thunderbird                     1:24.6.0+build1-0ubuntu0.12.04.1
