Several security issues were fixed in Thunderbird.
Multiple memory safety issues were discovered in Thunderbird. If a 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-2013-1739, CVE-2013-5590, CVE-2013-5591)

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 a 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-2013-1739, CVE-2013-5590, CVE-2013-5591)
Jordi Chancel discovered that HTML select elements could display arbitrary content. If a user had scripting enabled, an attacker could potentially exploit this to conduct URL spoofing or clickjacking attacks. (CVE-2013-5593)
Abhishek Arya discovered a crash when processing XSLT data in some circumstances. 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-2013-5604)
Dan Gohman discovered a flaw in the Javascript engine. If a user had enabled scripting, when combined with other vulnerabilities an attacker could possibly exploit this to execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2013-5595)
Ezra Pool discovered a crash on extremely large pages. 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-2013-5596)
Byoungyoung Lee discovered a use-after-free when updating the offline cache. If a user had scripting enabled, 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-2013-5597)
Multiple use-after-free flaws were discovered in Thunderbird. If a user had 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-2013-5599, CVE-2013-5600, CVE-2013-5601)
A memory corruption flaw was discovered in the Javascript engine when using workers with direct proxies. If a user had scripting enabled, 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-2013-5602)
Abhishek Arya discovered a use-after-free when interacting with HTML document templates. If a user had scripting enabled, 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-2013-5603)
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.
