Details:

Andrei Vaida, Jesse Ruderman, Bob Clary, and Jesse Ruderman
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 with the privileges of the user invoking
Thunderbird. (CVE-2015-7201)

Ronald Crane discovered a buffer overflow through code inspection. If a
user were tricked in to opening a specially crafted website in a browsing
context, 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-2015-7205)

Abhishek Arya discovered an integer overflow when allocating large
textures. If a user were tricked in to opening a specially crafted
website in a browsing context, 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-2015-7212)

Ronald Crane dicovered an integer overflow when processing MP4 format
video in some circumstances. If a user were tricked in to opening a
specially crafted website in a browsing context, 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-2015-7213)

Tsubasa Iinuma discovered a way to bypass same-origin restrictions using
data: and view-source: URLs. If a user were tricked in to opening a
specially crafted website in a browsing context, an attacker could
potentially exploit this to obtain sensitive information and read local
files. (CVE-2015-7214)
