(CVE-2015-0820)
Armin Razmdjou discovered that opening hyperlinks with specific mouse and key combinations could allow a Chrome privileged URL to be opened without context restrictions being preserved. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass security restrictions.
(CVE-2015-0821)
Armin Razmdjou discovered that contents of locally readable files could be made available via manipulation of form autocomplete in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2015-0822)
Atte Kettunen discovered a use-after-free in the OpenType Sanitiser (OTS) in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash. (CVE-2015-0823)

Atte Kettunen discovered a buffer underflow during playback of MP3 files in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2015-0825)
Atte Kettunen discovered a buffer overflow during CSS restyling in some circumstances. If a user were tricked in to opening a specially crafted website, 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-2015-0826)
Abhishek Arya discovered an out-of-bounds read and write when rendering SVG content in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2015-0827)
A buffer overflow was discovered in libstagefright during video playback in some circumstances. If a user were tricked in to opening a specially crafted website, 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-2015-0829)
Daniele Di Proietto discovered that WebGL could cause a crash in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service. (CVE-2015-0830)
Paul Bandha discovered a use-after-free in IndexedDB. If a user were tricked in to opening a specially crafted website, 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-2015-0831)
Muneaki Nishimura discovered that a period appended to a hostname could bypass key pinning and HSTS in some circumstances. A remote attacker could potentially exloit this to conduct a Man-in-the-middle (MITM) attack. (CVE-2015-0832)
Alexander Kolesnik discovered that Firefox would attempt plaintext connections to servers when handling turns: and stuns: URIs. A remote attacker could potentially exploit this by conducting a Man-in-the-middle (MITM) attack in order to obtain credentials.
(CVE-2015-0834)
Carsten Book, Christoph Diehl, Gary Kwong, Jan de Mooij, Liz Henry, Byron Campen, Tom Schuster, Ryan VanderMeulen, Christian Holler, Jesse Ruderman, Randell Jesup, Robin Whittleton, Jon Coppeard, and Nikhil Marathe 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-2015-0835, CVE-2015-0836).
