Jesse Ruderman, Mats Palmgren, Byron Campen, and Steve Fink 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-2015-2708)

Atte Kettunen discovered a buffer overflow during the rendering of SVG
content with certain CSS properties in some circumstances. If a user were

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-2015-2710)

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
denial of service via application crash, or execute arbitrary code with
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
