Details

Ben Turner, Bobby Holley, Jesse Ruderman, Christian Holler and Christoph
Diehl discovered multiple memory safety issues in Firefox. If a user were
tricked in to opening a specially crafted website, 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
Firefox. (CVE-2013-5609, CVE-2013-5610)

Myk Melez discovered that the doorhanger notification for web app
installation could persist between page navigations. An attacker could
potentially exploit this to conduct clickjacking attacks. (CVE-2013-5611)

Masato Kinugawa discovered that pages with missing character set encoding
information can inherit character encodings across navigations from
another domain. An attacker could potentially exploit this to conduct
cross-site scripting attacks. (CVE-2013-5612)

Daniel Veditz discovered that a sandboxed iframe could use an object
element to bypass its own restrictions. (CVE-2013-5614)

Tyson Smith and Jesse Schwartzentruber discovered a use-after-free in
event listeners. 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 Firefox. (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 Firefox. (CVE-2013-5618)

Dan Gohman discovered that binary search algorithms in Spidermonkey
used arithmetic prone to overflow in several places. However, this
is issue not believed to be exploitable. (CVE-2013-5619)

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

Vincent Lefevre discovered that web content could access clipboard data
under certain circumstances, resulting in information disclosure.
(CVE-2013-6672)

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. 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 Firefox. (CVE-2013-5613)

Eric Faust discovered that GetElementIC typed array stubs can be generated
outside observed typesets. 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)
