Several security issues were fixed in Thunderbird.
Benoit Jacob, Olli Pettay, Jan Varga, Jan de Mooij, Jesse Ruderman, Dan Gohman and Christoph Diehl 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-2014-1493)

Several security issues were fixed in Thunderbird.
Benoit Jacob, Olli Pettay, Jan Varga, Jan de Mooij, Jesse Ruderman, Dan Gohman and Christoph Diehl 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-2014-1493)
Atte Kettunen discovered an out-of-bounds read during WAV file decoding. If a user had enabled audio, an attacker could potentially exploit this to cause a denial of service via application crash. (CVE-2014-1497)
Robert O’Callahan discovered a mechanism for timing attacks involving SVG filters and displacements input to feDisplacementMap. If a user had enabled scripting, an attacker could potentially exploit this to steal confidential information across domains. (CVE-2014-1505)
Tyson Smith and Jesse Schwartzentruber discovered an out-of-bounds read during polygon rendering in MathML. If a user had enabled scripting, an attacker could potentially exploit this to steal confidential information across domains. (CVE-2014-1508)
John Thomson discovered a memory corruption bug in the Cairo graphics library. If a user had a malicious extension installed, 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-2014-1509)
Mariusz Mlynski discovered that web content could open a chrome privileged page and bypass the popup blocker in some circumstances. 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-2014-1510, CVE-2014-1511)
It was discovered that memory pressure during garbage collection resulted in memory corruption 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-2014-1512)
Jüri Aedla discovered out-of-bounds reads and writes with TypedArrayObject 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-2014-1513)
George Hotz discovered an out-of-bounds write with TypedArrayObject. 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-2014-1514)
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.
