Christian Holler, Andrew McCreight, Dan Minor, Tyson Smith, Jon Coppeard, Jan-Ivar Bruaroey, Jesse Ruderman, Markus Stange, Olli Pettay, Ehsan Akhgari, Gary Kwong, Tooru Fujisawa, and Randell Jesup 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. (CVE-2016-5289, CVE-2016-5290)

A same-origin policy bypass was discovered with local HTML files in some circumstances. An attacker could potentially exploit this to obtain sensitive information. (CVE-2016-5291)

A crash was discovered when parsing URLs in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to execute arbitrary code. (CVE-2016-5292)

A heap buffer-overflow was discovered in Cairo when processing SVG content. 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. (CVE-2016-5296)
