Firefox. (CVE-2014-1574, CVE-2014-1575)

Abhishek Arya discovered an out-of-bounds write when buffering WebM video
in some circumstances. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to cause a

the privileges of the user invoking Firefox. (CVE-2014-1578)

Michal Zalewski discovered that memory may not be correctly initialized
when rendering a malformed GIF in to a canvas in some circumstances. If

Patrick McManus and David Keeler discovered 2 issues that could result
in certificate pinning being bypassed in some circumstances. An attacker
with a fraudulent certificate could potentially exploit this conduct a
machine-in-the-middle attack. (CVE-2014-1582, CVE-2014-1584)

Eric Shepherd and Jan-Ivar Bruaroey discovered issues with video sharing
via WebRTC in iframes, where video continues to be shared after being

user being aware. (CVE-2014-1585, CVE-2014-1586)

Boris Zbarsky discovered that webapps could use the Alarm API to read the
values of cross-origin references. If a user were tricked in to installing
