browsing context, an attacker could potentially exploit this to cause
a denial of service via application crash, or execute arbitrary code.
(CVE-2016-5274)

A use-after-free was discovered in accessibility. If a user were
tricked in to opening a specially crafted website in a browsing
context, an attacker could potentially exploit this to cause a denial
of service via application crash, or execute arbitrary code.
(CVE-2016-5276)

A use-after-free was discovered in web animations when destroying a
timeline. If a user were tricked in to opening a specially crafted
website in a browsing context, an attacker could potentially exploit
this to cause a denial of service via application crash, or execute
arbitrary code. (CVE-2016-5277)

A buffer overflow was discovered when encoding image frames to images
in some circumstances. If a user were tricked in to opening a
specially crafted message, an attacker could potentially exploit this
to cause a denial of service via application crash, or execute
arbitrary code. (CVE-2016-5278)

Mei Wang discovered a use-after-free when changing text direction. If
a user were tricked in to opening a specially crafted website in a
browsing context, an attacker could potentially exploit this to cause

(CVE-2016-5280)

Brian Carpenter discovered a use-after-free when manipulating SVG
content in some circumstances. If a user were tricked in to opening a
specially crafted website in a browsing context, an attacker could
potentially exploit this to cause a denial of service via application
crash, or execute arbitrary code. (CVE-2016-5281)

An issue was discovered with the preloaded Public Key Pinning (HPKP).
If a man-in-the-middle (MITM) attacker was able to obtain a fraudulent
certificate for a Mozilla site, they could exploit this by providing
malicious addon updates. (CVE-2016-5284).
