Mozilla Firefox < 52.0 Multiple Vulnerabilities (macOS)

Synopsis :

The remote macOS or Mac OS X host contains a web browser that is
affected by multiple vulnerabilities.

Description :

The version of Mozilla Firefox installed on the remote macOS or Mac
OS X host is prior to 52.0. It is, therefore, affected by
multiple vulnerabilities :

- Mozilla developers and community members Boris Zbarsky,
Christian Holler, Honza Bambas, Jon Coppeard, Randell
Jesup, Andre Bargull, Kan-Ru Chen, and Nathan Froyd
reported memory safety bugs present in Firefox 51 and
Firefox ESR 45.7. 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-2017-5398)

- Mozilla developers and community members Carsten Book,
Calixte Denizet, Christian Holler, Andrew McCreight,
David Bolter, David Keeler, Jon Coppeard, Tyson Smith,
Ronald Crane, Tooru Fujisawa, Ben Kelly, Bob Owen, Jed
Davis, Julian Seward, Julian Hector, Philipp, Markus
Stange, and Andre Bargull reported memory safety bugs
present 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-2017-5399)

- JIT-spray targeting asm.js combined with a heap spray
allows for a bypass of ASLR and DEP protections leading
to potential memory corruption attacks. (CVE-2017-5400)

- A crash triggerable by web content in which an
ErrorResult references unassigned memory due to a logic
error. The resulting crash may be exploitable.
(CVE-2017-5401)

- A use-after-free can occur when events are fired for a
FontFace object after the object has been already been
destroyed while working with fonts. This results in a
potentially exploitable crash. (CVE-2017-5402)

- When adding a range to an object in the DOM, it is
possible to use addRange to add the range to an
incorrect root object. This triggers a use-after-free,
resulting in a potentially exploitable crash.
(CVE-2017-5403)

- A use-after-free error can occur when manipulating
ranges in selections with one node inside a native
anonymous tree and one node outside of it. This results
in a potentially exploitable crash. (CVE-2017-5404)

- Certain response codes in FTP connections can result in
the use of uninitialized values for ports in FTP
operations. (CVE-2017-5405)

- A segmentation fault can occur in the Skia graphics
library during some canvas operations due to issues
with mask/clip intersection and empty masks.
(CVE-2017-5406)

- Using SVG filters that don't use the fixed point math
implementation on a target iframe, a malicious page can
extract pixel values from a targeted user. This can be
used to extract history information and read text
values across domains. This violates same-origin policy
and leads to information disclosure. (CVE-2017-5407)

- Video files loaded video captions cross-origin without
checking for the presence of CORS headers permitting
such cross-origin use, leading to potential information
disclosure for video captions. (CVE-2017-5408)

- Memory corruption resulting in a potentially
exploitable crash during garbage collection of
JavaScript due errors in how incremental sweeping is
managed for memory cleanup. (CVE-2017-5410)

- A buffer overflow read during SVG filter color value
operations, resulting in data exposure. (CVE-2017-5412)

- A segmentation fault can occur during some
bidirectional layout operations. (CVE-2017-5413)

- The file picker dialog can choose and display the wrong
local default directory when instantiated. On some
operating systems, this can lead to information
disclosure, such as the operating system or the local
account name. (CVE-2017-5414)

- An attack can use a blob URL and script to spoof an
arbitrary addressbar URL prefaced by blob: as the
protocol, leading to user confusion and further
spoofing attacks. (CVE-2017-5415)

- In certain circumstances a networking event listener
can be prematurely released. This appears to result in
a null dereference in practice. (CVE-2017-5416)

- When dragging content from the primary browser pane to
the addressbar on a malicious site, it is possible to
change the addressbar so that the displayed location
following navigation does not match the URL of the
newly loaded page. This allows for spoofing attacks.
(CVE-2017-5417)

- An out of bounds read error occurs when parsing some
HTTP digest authorization responses, resulting in
information leakage through the reading of random
memory containing matches to specifically set patterns.
(CVE-2017-5418)

- If a malicious site repeatedly triggers a modal
authentication prompt, eventually the browser UI will
become non-responsive, requiring shutdown through the
operating system. This is a denial of service (DOS)
attack. (CVE-2017-5419)

- A javascript: url loaded by a malicious page can
obfuscate its location by blanking the URL displayed in
the addressbar, allowing for an attacker to spoof an
existing page without the malicious page's address
being displayed correctly. (CVE-2017-5420)

- A malicious site could spoof the contents of the print
preview window if popup windows are enabled, resulting
in user confusion of what site is currently loaded.
(CVE-2017-5421)

- If a malicious site uses the view-source: protocol in a
series within a single hyperlink, it can trigger a
non-exploitable browser crash when the hyperlink is
selected. This was fixed by no longer making
view-source: linkable. (CVE-2017-5422)

- The Gecko Media Plugin sandbox allows access to local
files that match specific regular expressions. On OS
OX, this matching allows access to some data in
subdirectories of /private/var that could expose
personal or temporary data. This has been updated to
not allow access to /private/var and its
subdirectories. Note: this issue only affects OS X.
Other operating systems are not affected.
(CVE-2017-5425)

- A non-existent chrome.manifest file will attempt to be
loaded during startup from the primary installation
directory. If a malicious user with local access puts
chrome.manifest and other referenced files in this
directory, they will be loaded and activated during
startup. This could result in malicious software being
added without consent or modification of referenced
installed files. (CVE-2017-5427)

Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues.
