Details

Multiple memory safety issues were discovered in Thunderbird. If the user
were tricked into 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 code with the
privileges of the user invoking Thunderbird. (CVE-2013-0801,
CVE-2013-1669)

Cody Crews discovered that some constructors could be used to bypass
restrictions enforced by their Chrome Object Wrapper (COW). If a user had
scripting enabled, an attacker could exploit this to conduct cross-site
scripting (XSS) attacks. (CVE-2013-1670)

A use-after-free was discovered when resizing video content whilst it is
playing. If a user had scripting enabled, an attacker could potentially
exploit this to execute code with the privileges of the user invoking
Thunderbird. (CVE-2013-1674)

It was discovered that some DOMSVGZoomEvent functions could be used
without being properly initialized, which could lead to information
leakage. (CVE-2013-1675)

Abhishek Arya discovered multiple memory safety issues in Thunderbird. If
the user were tricked into opening a specially crafted message, an
attacker could possibly exploit these to cause a denial of service via
application crash, or potentially execute code with the privileges of
the user invoking Thunderbird. (CVE-2013-1676, CVE-2013-1677,
CVE-2013-1678, CVE-2013-1679, CVE-2013-1680, CVE-2013-1681)
