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

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)

An error was discovered in argument length checking in Javascript. 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-2016-5297)

An integer overflow was discovered in the Expat library. 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-2016-9063)

It was discovered that addon updates failed to verify that the addon ID
inside the signed package matched the ID of the addon being updated.
An attacker that could perform a machine-in-the-middle (MITM) attack could
potentially exploit this to provide malicious addon updates.
(CVE-2016-9064)

A buffer overflow was discovered in nsScriptLoadHandler. 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-2016-9066)

2 use-after-free bugs were discovered during DOM operations in some
circumstances. 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-2016-9067,
CVE-2016-9069)

A heap use-after-free was discovered during web animations 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. (CVE-2016-9068)

It was discovered that a page loaded in to the sidebar through a bookmark
could reference a privileged chrome window. An attacker could potentially
exploit this to bypass same origin restrictions. (CVE-2016-9070)

An issue was discovered with Content Security Policy (CSP) in combination
with HTTP to HTTPS redirection. An attacker could potentially exploit this
to verify whether a site is within the user's browsing history.
(CVE-2016-9071)

user were tricked in to installing a malicious extension, an attacker
could potentially exploit this to escape the WebExtensions sandbox.
(CVE-2016-9073)

It was discovered that WebExtensions can use the mozAddonManager API. An
attacker could potentially exploit this to install additional extensions
without user permission. (CVE-2016-9075)

It was discovered that <select> element dropdown menus can cover location
bar content when e10s is enabled. An attacker could potentially exploit
this to conduct UI spoofing attacks. (CVE-2016-9076)

It was discovered that canvas allows the use of the feDisplacementMap
filter on cross-origin images. An attacker could potentially exploit this
to conduct timing attacks. (CVE-2016-9077)
