Christian Holler and Patrick McManus 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-2014-8634)

Muneaki Nishimura discovered that requests from navigator.sendBeacon() lack an origin header. If a user were tricked in to opening a specially crafted message with scripting enabled, an attacker could potentially exploit this to conduct cross-site request forgery (XSRF) attacks. (CVE-2014-8638)

Xiaofeng Zheng discovered that a web proxy returning a 407 response could inject cookies in to the originally requested domain. If a user connected to a malicious web proxy, an attacker could potentially exploit this to conduct session-fixation attacks. (CVE-2014-8639).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
