Mozilla Firefox ESR < 45.8 Multiple Vulnerabilities

Synopsis :

The remote Windows host contains a web browser that is affected by
multiple vulnerabilities.

Description :

The version of Mozilla Firefox ESR installed on the remote Windows
host is prior to 45.8. 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)

- 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)

- 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)

- 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)

- The Mozilla Windows updater can be called by a
non-privileged user to delete an arbitrary local file
by passing a special path to the callback parameter
through the Mozilla Maintenance Service, which has
privileged access. Note: This attack requires local
system access and only affects Windows. Other operating
systems are not affected. (CVE-2017-5409)

- 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)

Note that Tenable Network Security has extracted the preceding
description block directly from the Mozilla security advisories.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues.
