Several security issues were fixed in Thunderbird.
Jeff Gilbert and Henrik Skupin discovered multiple memory safety issues in Thunderbird. If the user were tricked in to 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-2013-1701)

A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in Thunderbird.
Jeff Gilbert and Henrik Skupin discovered multiple memory safety issues in Thunderbird. If the user were tricked in to 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-2013-1701)
It was discovered that a document’s URI could be set to the URI of a different document. If a user had scripting enabled, an attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2013-1709)
A flaw was discovered when generating a CRMF request in certain circumstances. If a user had scripting enabled, an attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2013-1710)
Cody Crews discovered that some Javascript components performed security checks against the wrong URI, potentially bypassing same-origin policy restrictions. If a user had scripting enabled, an attacker could exploit this to conduct cross-site scripting (XSS) attacks or install addons from a malicious site. (CVE-2013-1713)
Federico Lanusse discovered that web workers could bypass cross-origin checks when using XMLHttpRequest. If a user had scripting enabled, an attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2013-1714)
Georgi Guninski and John Schoenick discovered that Java applets could access local files under certain circumstances. If a user had scripting enabled, an attacker could potentially exploit this to steal confidential data. (CVE-2013-1717)
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.
