Speculative execution side-channel attack ("Spectre")
Announced
January 4, 2018
Reporter
Jann Horn (Google Project Zero); Microsoft Vunerability Research
Impact
High
Products
Firefox
Fixed in
Firefox 57.0.4
Description
Jann Horn of Google Project Zero Security reported that speculative
execution performed by modern CPUs could leak information through
a timing side-channel attack. Microsoft Vulnerability Research extended
this attack to browser JavaScript engines and demonstrated that code on
a malicious web page could read data from other web sites (violating
the same-origin policy) or private data from the browser itself.
Since this new class of attacks involves measuring precise time intervals,
as a partial, short-term, mitigation we are disabling or reducing
the precision of several time sources in Firefox. The precision of
performance.now() has been reduced from 5us to 20us, and
the SharedArrayBuffer feature has been disabled because it can be
used to construct a high-resolution timer.
SharedArrayBuffer is already disabled in Firefox 52 ESR.
Changelog:
Fixed
Fix a video color distortion issue on YouTube and other video sites
with some AMD devices (bug 1417442)

Fixed
Various security fixes
Changed
Firefox now exclusively supports extensions built using the
WebExtension API, and unsupported legacy extensions will no
longer work. Learn more about our efforts to improve the
performance and security of extensions
The browser's autoscroll feature, as well as scrolling by
keyboard input and touch-dragging of scrollbars, now use
asynchronous scrolling. These scrolling methods are now similar
to other input methods like mousewheel, and provide a smoother
scrolling experience
The content process now has a stricter security sandbox that
blocks filesystem reading and writing on Linux, similar to the
protections for Windows and macOS that shipped in Firefox 56
Middle mouse paste in the content area no longer navigates to
URLs by default on Unix systems
Removed the toolbar Share button. If you relied on this feature,
you can install the Share Backported extension instead.
Some older versions of the ATOK IME, including ATOK 2006, 2008,
2009 and 2010, can cause crashes and are therefore disabled on
the Windows 64-bit version of Firefox Quantum. To fix those
incompatibility issues, please use a newer version of ATOK or
one of other IMEs.
The default font for Japanese text is now Meiryo

#CVE-2017-7832: Domain spoofing through use of dotless 'i' character
followed by accent markers
Reporter
Jonathan Kew
Impact
moderate
Description
The combined, single character, version of the letter 'i' with any
of the potential accents in unicode, such as acute or grave, can
be spoofed in the addressbar by the dotless version of 'i' followed
by the same accent as a second character with most font sets. This
allows for domain spoofing attacks because these combined domain
names do not display as punycode.

Impact
moderate
Description
Some Arabic and Indic vowel marker characters can be combined with
Latin characters in a domain name to eclipse the non-Latin character
with some font sets on the addressbar. The non-Latin character will
not be visible to most viewers. This allows for domain spoofing
attacks because these combined domain names do not display as
punycode.

Description
A data: URL loaded in a new tab did not inherit the Content Security
Policy (CSP) of the original page, allowing for bypasses of the
policy including the execution of JavaScript. In prior versions
when data: documents also inherited the context of the original
page this would allow for potential cross-site scripting (XSS)
attacks.

Description
The "pingsender" executable used by the Firefox Health Report
dynamically loads a system copy of libcurl, which an attacker could
replace. This allows for privilege escalation as the replaced
libcurl code will run with Firefox's privileges. Note: This attack
requires an attacker have local system access and only affects OS
X and Linux. Windows systems are not affected.

#CVE-2017-7839: Control characters before javascript: URLs defeats
self-XSS prevention mechanism
Reporter
Eric Lawrence
Impact
low
Description
Control characters prepended before javascript: URLs pasted in the
addressbar can cause the leading characters to be ignored and the
pasted JavaScript to be executed instead of being blocked. This
could be used in social engineering and self-cross-site-scripting
(self-XSS) attacks where users are convinced to copy and paste text
into the addressbar.

placing JavaScript code into user-supplied tags in saved bookmarks.
If the resulting exported HTML file is later opened in a browser
this JavaScript will be executed. This could be used in social

Changelog:
New
Added support for WebAssembly, an emerging standard that brings near-native performance to Web-based games, apps, and software libraries without the use of plugins.
Added automatic captive portal detection, for easier access to Wi-Fi hotspots. When accessing the Internet via a captive portal, Firefox will alert users and open the portal login page in a new tab.
Added user warnings for non-secure HTTP pages with logins. Firefox now displays a "This connection is not secure" message when users click into the username and password fields on pages that don't use HTTPS.
Implemented the Strict Secure Cookies specification which forbids insecure HTTP sites from setting cookies with the "secure" attribute. In some cases, this will prevent an insecure site from setting a cookie with the same name as an existing "secure" cookie from the same base domain.
Enhanced Sync to allow users to send and open tabs from one device to another.
Fixed
Various security fixes
Improved text input for third-party keyboard layouts on Windows. This will address some keyboard layouts that
* have chained dead keys
* input two or more characters with a non-printable key or a dead key sequence
* input a character even when a dead key sequence failed to compose a character
Changed
Removed support for Netscape Plugin API (NPAPI) plugins other than Flash. Silverlight, Java, Acrobat and the like are no longer supported.
Removed Battery Status API to reduce fingerprinting of users by trackers
Improved experience for downloads:
* Notification in the toolbar when a download fails
* Quick access to five most recent downloads rather than three
* Larger buttons for canceling and restarting downloads
Display (but allow users to override) an "Untrusted Connection" error when encountering SHA-1 certificates that chain up to a root certificate included in Mozilla's CA Certificate Program. (Note: Firefox continues to permit SHA-1 certificates that chain to manually imported root certificates.) Read more about the Mozilla Security Team's plans to deprecate SHA-1
Migrated Firefox users on Windows XP and Windows Vista operating systems to the extended support release (ESR) version of Firefox.
When not using Direct2D on Windows, Skia is used for content rendering
Developer
Enabled CSS Grid Layout, opening up a world of new possibilities for graphic design
Redesigned Responsive Design Mode to include device selection, network throttling, and more
Improved security for screen sharing, which now shows a preview and no longer requires a whitelisted domain

Add-on development just got easier because you can reload them from about:debugging — because we're all about debugging.
This theme is hot, hot, hot! Say hi to the Firebug theme for Developer Tools.
