Details

Gary Kwong, Christoph Diehl, Christian Holler, Hannes Verschore, Jan de
Mooij, Ryan VanderMeulen, Jeff Walden and Kyle Huey 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-2014-1533)

Abhishek Arya discovered multiple use-after-free and out-of-bounds read
issues in Thunderbird. If a user had enabled scripting, an attacker could
potentially exploit these to cause a denial of service via application
crash or execute arbitrary code with the priviliges of the user invoking
Thunderbird. (CVE-2014-1538)

A use-after-free was discovered in the SMIL animation controller. 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 priviliges of the user invoking Thunderbird. (CVE-2014-1541)

The problem can be corrected by updating your system to the following package versions:
