Several security issues were fixed in Thunderbird.
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)

Several security issues were fixed in Thunderbird.
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)
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.
