Multiple memory safety issues were discovered in Thunderbird. If a user were tricked in to opening a specially crafted message with scripting enabled, an attacker could possibly exploit these to cause a denial of service via application crash, or potentially execute arbitrary code with the privileges of the user invoking Thunderbird. Atte Kettunen discovered a flaw in the HTML5 Tree Builder when interacting with template elements. If a user had scripting enabled, in some circumstances an attacker could potentially exploit this to execute arbitrary code with the privileges of the user invoking Thunderbird. Various other issues were also addressed.
