Several security issues were fixed in Thunderbird.
Multiple memory safety issues were discovered in Thunderbird. If the user were tricked into 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.

A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in Thunderbird.
Multiple memory safety issues were discovered in Thunderbird. If the user were tricked into 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-2013-1682)
Abhishek Arya discovered multiple use-after-free bugs. If the user were tricked into opening a specially crafted message with scripting enabled, an attacker could possibly exploit these to execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2013-1684, CVE-2013-1685, CVE-2013-1686)
Mariusz Mlynski discovered that user defined code within the XBL scope of an element could be made to bypass System Only Wrappers (SOW). 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-2013-1687)
A crash was discovered when reloading a page that contained content using the onreadystatechange event. 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-2013-1690)
Johnathan Kuskos discovered that Thunderbird sent data in the body of XMLHttpRequest HEAD requests. If a user had scripting enabled, an attacker could exploit this to conduct Cross-Site Request Forgery (CSRF) attacks. (CVE-2013-1692)
Paul Stone discovered a timing flaw in the processing of SVG images with filters. If a user had scripting enabled, an attacker could exploit this to view sensitive information. (CVE-2013-1693)
Boris Zbarsky discovered a flaw in PreserveWrapper. If a user had scripting enabled, an attacker could potentially exploit this to cause a denial of service via application crash, or execute code with the privileges of the user invoking Thunderbird. (CVE-2013-1694)
It was discovered that XrayWrappers could be bypassed to call content-defined methods in certain circumstances. If a user had scripting enabled, an attacker could exploit this to cause undefined behaviour. (CVE-2013-1697)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to restart Thunderbird to make all the necessary changes.
