Badea 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-2014-1547, CVE-2014-1548)

Atte Kettunen discovered a buffer overflow when interacting with
WebAudio buffers. 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-2014-1549)

Atte Kettunen discovered a use-after-free in WebAudio. 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-2014-1550)

David Chan and Gijs Kruitbosch discovered that web content could spoof
UI customization events in some circumstances, resulting in a limited
ability to move UI icons. (CVE-2014-1561)

Jethro Beekman discovered a use-after-free when the FireOnStateChange
event is triggered in some circumstances. An attacker could
potentially exploit this to cause a denial of service via application
crash or execute arbitrary code with the priviliges of the user
invoking Firefox. (CVE-2014-1555)

Patrick Cozzi discovered a crash when using the Cesium JS library to
generate WebGL content. An attacker could potentially exploit this to
execute arbitrary code with the privilges of the user invoking
Firefox. (CVE-2014-1556)

Tyson Smith and Jesse Schwartzentruber discovered a use-after-free in
CERT_DestroyCertificate. 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-2014-1544)

A crash was discovered in Skia when scaling an image, if the scaling
operation takes too long. An attacker could potentially exploit this
to execute arbitrary code with the privileges of the user invoking
Firefox. (CVE-2014-1557)

Christian Holler discovered several issues when parsing certificates
with non-standard character encoding, resulting in the inability to
use valid SSL certificates in some circumstances. (CVE-2014-1558,
CVE-2014-1559, CVE-2014-1560)

Boris Zbarsky discovered that network redirects could cause an iframe
to escape the confinements defined by its sandbox attribute in some
circumstances. An attacker could potentially exploit this to conduct
cross-site scripting attacks. (CVE-2014-1552).
