Scott Bell discovered a use-afer-free during the processing of text when
vertical text is enabled. If a user were tricked in to opening a specially
crafted message, an attacker could potentially exploit this to cause a

the privileges of the user invoking Thunderbird. (CVE-2015-2713)

Ucha Gobejishvili discovered a buffer overflow when parsing compressed XML
content. If a user were tricked in to opening a specially crafted message
with scripting enabled, 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-2015-2716)
