Several security issues were fixed in Thunderbird.
Christian Holler, Jon Coppeard, Olli Pettay, Ehsan Akhgari, Gary Kwong, Tooru Fujisawa, and Randell Jesup discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code.
