Details

Ben Turner, Bobby Holley, Jesse Ruderman and Christian Holler 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-2013-5609)

Tyson Smith and Jesse Schwartzentruber discovered a use-after-free in
event listeners. If a user had enabled scripting, 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-2013-5616)

A use-after-free was discovered in the table editing interface. 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-2013-5618)

Tyson Smith and Jesse Schwartzentruber discovered a crash when inserting
an ordered list in to a document using script. If a user had enabled
scripting, an attacker could potentially exploit this to execute
arbitrary code with the privileges of the user invoking Thunderbird.
(CVE-2013-6671)

Sijie Xia discovered that trust settings for built-in EV root certificates
were ignored under certain circumstances, removing the ability for a user
to manually untrust certificates from specific authorities.
(CVE-2013-6673)

Tyson Smith, Jesse Schwartzentruber and Atte Kettunen discovered a
use-after-free in functions for synthetic mouse movement handling. If a
user had enabled scripting, 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-2013-5613)

Eric Faust discovered that GetElementIC typed array stubs can be generated
outside observed typesets. If a user had enabled scripting, an attacker
could possibly exploit this to cause undefined behaviour with a potential
security impact. (CVE-2013-5615)

Michal Zalewski discovered several issues with JPEG image handling. An
attacker could potentially exploit these to obtain sensitive information.
(CVE-2013-6629, CVE-2013-6630)
