Several security issues were fixed in Thunderbird.
Bobby Holley, Carsten Book, Christoph Diehl, Gary Kwong, Jan de Mooij, Jesse Ruderman, Nathan Froyd 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-2014-1518)

Several security issues were fixed in Thunderbird.
Bobby Holley, Carsten Book, Christoph Diehl, Gary Kwong, Jan de Mooij, Jesse Ruderman, Nathan Froyd 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-2014-1518)
Abhishek Arya discovered an out of bounds read when decoding JPG images. An attacker could potentially exploit this to cause a denial of service via application crash. (CVE-2014-1523)
Abhishek Arya discovered a buffer overflow when a script uses a non-XBL object as an XBL object. 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-2014-1524)
Mariusz Mlynski discovered that sites with notification permissions can run script in a privileged context in some circumstances. If a user had enabled scripting, an attacker could exploit this to execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2014-1529)
It was discovered that browser history navigations could be used to load a site with the addressbar displaying the wrong address. If a user had enabled scripting, an attacker could potentially exploit this to conduct cross-site scripting or phishing attacks. (CVE-2014-1530)
A use-after-free was discovered when resizing images in some circumstances. 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-2014-1531)
Tyson Smith and Jesse Schwartzentruber discovered a use-after-free during host resolution in some circumstances. 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-2014-1532)
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.
