Summary
=======

The package firefox before version 51.0.1-1 is vulnerable to multiple
issues including arbitrary code execution, access restriction bypass,
information disclosure, privilege escalation, arbitrary file overwrite,
content spoofing and denial of service.

Resolution
==========

Upgrade to 51.0.1-1.

# pacman -Syu "firefox>=51.0.1-1"

The problems have been fixed upstream in version 51.0.

Workaround
==========

None.

Description
===========

- CVE-2017-5373 (arbitrary code execution)

Several memory safety bugs have been found in Firefox < 51 and
Thunderbird < 47.5. Some of these bugs showed evidence of memory
corruption and we presume that with enough effort that some of these
could be exploited to run arbitrary code.

- CVE-2017-5374 (arbitrary code execution)

Several memory safety bugs have been found in Firefox < 51. Some of
these bugs showed evidence of memory corruption and we presume that
with enough effort that some of these could be exploited to run
arbitrary code.

- CVE-2017-5375 (arbitrary code execution)

JIT code allocation in Firefox < 51 and Thunderbird < 45.7 can allow
for a bypass of ASLR and DEP protections leading to potential memory
corruption attacks.

- CVE-2017-5376 (arbitrary code execution)

A use-after-free vulnerability has been found in Firefox < 51 and
Thunderbird < 45.7, while manipulating XSL in XSLT documents.

- CVE-2017-5377 (arbitrary code execution)

A memory corruption vulnerability in Skia that can occur when using
transforms to make gradients, resulting in a potentially exploitable
crash.

- CVE-2017-5378 (information disclosure)

An information disclosure vulnerability has been found in Firefox < 51
and Thunderbird < 45.7, where hashed codes of JavaScript objects are
shared between pages. This allows for pointer leaks because an object’s
address can be discovered through hash codes, and also allows for data
leakage of an object’s content using these hash codes.

- CVE-2017-5379 (arbitrary code execution)

A use-after-free vulnerability has been found in Firefox < 51, in Web
Animations, when interacting with cycle collection.

- CVE-2017-5380 (arbitrary code execution)

A potential use-after-free vulnerability during DOM manipulation of SVG
content has been in Firefox < 51 and Thunderbird < 45.7.

- CVE-2017-5381 (arbitrary file overwrite)

The "export" function in the Firefox < 51 Certificate Viewer can force
local filesystem navigation when the "common name" in a certificate
contains slashes, allowing certificate content to be saved in unsafe
locations with an arbitrary filename.

- CVE-2017-5382 (information disclosure)

Feed preview for RSS feeds in Firefox < 51 can be used to capture
errors and exceptions generated by privileged content, allowing for the
exposure of internal information not meant to be seen by web content.

- CVE-2017-5383 (content spoofing)

URLs containing certain unicode glyphs for alternative hyphens and
quotes do not properly trigger punycode display in Firefox < 51 and
Thunderbird < 45.7, allowing for domain name spoofing attacks in the
location bar.

- CVE-2017-5384 (information disclosure)

Proxy Auto-Config (PAC) files in Firefox < 51 can specify a JavaScript
function called for all URL requests with the full URL path which
exposes more information than would be sent to the proxy itself in the
case of HTTPS. Normally the Proxy Auto-Config file is specified by the
user or machine owner and presumed to be non-malicious, but if a user
has enabled Web Proxy Auto Detect (WPAD) this file can be served
remotely.

- CVE-2017-5385 (information disclosure)

In Firefox < 51, data sent with in multipart channels, such as the
multipart/x-mixed-replace MIME type, will ignore the referrer-policy
response header, leading to potential information disclosure for sites
using this header.

- CVE-2017-5386 (privilege escalation)

WebExtension scripts in Firefox < 51 can use the data: protocol to
affect pages loaded by other web extensions using this protocol,
leading to potential data disclosure or privilege escalation in
affected extensions.

- CVE-2017-5387 (information disclosure)

The existence of a specifically requested local file can be found in
Firefox < 51 due to the double firing of the onerror when the source
attribute on a <track> tag refers to a file that does not exist if the
source page is loaded locally.

- CVE-2017-5388 (denial of service)

In Firefox < 51, a STUN server in conjunction with a large number of
webkitRTCPeerConnection objects can be used to send large STUN packets
in a short period of time due to a lack of rate limiting being applied
on e10s systems, allowing for a denial of service attack.

- CVE-2017-5389 (access restriction bypass)

WebExtensions in Firefox < 51 could use the mozAddonManager API by
modifying the CSP headers on sites with the appropriate permissions and
then using host requests to redirect script loads to a malicious site.
This allows a malicious extension to then install additional extensions
without explicit user permission.

- CVE-2017-5390 (privilege escalation)

The JSON viewer in the Developer Tools in Firefox < 51 and Thunderbird
< 45.7 uses insecure methods to create a communication channel for
copying and viewing JSON or HTTP headers data, allowing for potential
privilege escalation.

- CVE-2017-5391 (privilege escalation)

In Firefox < 51, special about: pages used by web content, such as RSS
feeds, can load privileged about: pages in an iframe. If a content-
injection bug were found in one of those pages this could allow for
potential privilege escalation.

- CVE-2017-5393 (access restriction bypass)

The mozAddonManager in Firefox < 51 allows for the installation of
extensions from the CDN for addons.mozilla.org, a publicly accessible
site. This could allow malicious extensions to install additional
extensions from the CDN in combination with an XSS attack on Mozilla
AMO sites.

- CVE-2017-5396 (arbitrary code execution)

A use-after-free vulnerability has been found in the Media Decoder of
Firefox < 51 and Thunderbird < 45.7, when working with media files when
some events are fired after the media elements are freed from memory.

Impact
======

A remote attacker can access sensitive information, bypass access
restrictions, overwrite arbitrary files, spoof content, escalate
privileges and execute arbitrary code on the affected host.
