OVERVIEW
A number of vulnerabilities have been identified in Mozilla Firefox
prior to version 20.0, Firefox ESR prior to version 17.0.5,
Thunderbird prior to version 17.0.5, Thunderbird ESR prior to version
17.0.5, and SeaMonkey prior to version 2.17.
IMPACT
The vendor has provided the following details regarding these
vulnerabilities:
MFSA 2013-30: "Mozilla developers identified and fixed several
memory safety bugs in the browser engine used in Firefox and other
Mozilla-based products. Some of these bugs showed evidence of memory
corruption under certain circumstances, and we presume that with
enough effort at least some of these could be exploited to run
arbitrary code.
Olli Pettay, Jesse Ruderman, Boris Zbarsky, Christian Holler, Milan
Sreckovic, and Joe Drew reported memory safety problems and crashes
that affect Firefox ESR 17, and Firefox 19.
Memory safety bugs fixed in Firefox 17.0.5 and Firefox 20.0
(CVE-2013-0788)
Andrew McCreight, Randell Jesup, Gary Kwong, Jesse Ruderman,
Christian Holler, and Mats Palmgren reported memory safety problems
and crashes that affect Firefox 19.
Memory safety bugs fixed in Firefox 20.0 (CVE-2013-0789)
Jim Chen reported a memory safety problem that affects Firefox for
Android 19.
Stack corruption in plug-in code (CVE-2013-0790)" [1]
MFSA 2013-31: "Security researcher Abhishek Arya (Inferno) of the
Google Chrome Security Team used the Address Sanitizer tool to
discover an out-of-bounds write in Cairo graphics library. When
certain values are passed to it during rendering, Cairo attempts to
use negative boundaries or sizes for boxes, leading to a potentially
exploitable crash in some instances.
OOB Write in pixman_fill_sse2 (CVE-2013-0800)" [2]
MFSA 2013-32: "Security researcher Frédéric Hoguin discovered that
the Mozilla Maintenance Service on Windows was vulnerable to a
buffer overflow. This system is used to update software without
invoking the User Account Control (UAC) prompt. The Mozilla
Maintenance Service is configured to allow unprivileged users to
start it with arbitrary arguments. By manipulating the data passed
in these arguments, an attacker can execute arbitrary code with the
system privileges used by the service. This issue requires local
file system access to be exploitable.
Mozilla Maintenance Service buffer overflow (CVE-2013-0799)" [3]
MFSA 2013-33: "Security researcher Shuichiro Suzuki of the
Fourteenforty Research Institute reported the app_tmp directory is
set to be world readable and writeable by Firefox for Android. This
potentially allows for third party applications to replace or alter
Firefox add-ons when downloaded because they are temporarily stored
in the app_tmp directory before installation.
Installation directory rights allows all (CVE-2013-0798)" [4]
MSFA 2013-34: "Security researcher Ash reported an issue with the
Mozilla Updater. The Mozilla Updater can be made to load a malicious
local DLL file in a privileged context through either the Mozilla
Maintenance Service or independently on systems that do not use the
service. This occurs when the DLL file is placed in a specific
location on the local system before the Mozilla Updater is run.
Local file system access is necessary in order for this issue to be
exploitable.
DLL planting vulnerability in Mozilla updater (CVE-2013-0797)" [5]
MFSA 2013-35: "Security researcher miaubiz used the Address
Sanitizer tool to discover a crash in WebGL rendering when memory is
freed that has not previously been allocated. This issue only
affects Linux users who have Intel Mesa graphics drivers. The
resulting crash could be potentially exploitable.
freeing unallocated address with webgl (CVE-2013-0796)" [6]
MFSA 2013-36: "Security researcher Cody Crews reported a mechanism
to use the cloneNode method to bypass System Only Wrappers (SOW) and
clone a protected node. This allows violation of the browser's same
origin policy and could also lead to privilege escalation and the
execution of arbitrary code.
Bypass of SOW protections allows cloning of protected node
(CVE-2013-0795)" [7]
MFSA 2013-37: "Security researcher shutdown reported a method for
removing the origin indication on tab-modal dialog boxes in
combination with browser navigation. This could allow an attacker's
dialog to overlay a page and show another site's content. This can
be used for phishing by allowing users to enter data into a modal
prompt dialog on an attacking, site while appearing to be from the
displayed site.
Tab modal dialog spoofing (CVE-2013-0794)" [8]
MFSA 2013-38: "Security researcher Mariusz Mlynski reported a method
to use browser navigations through history to load an arbitrary
website with that page's baseURI property pointing to another site
instead of the seemingly loaded one. The user will continue to see
the incorrect site in the addressbar of the browser. This allows for
a cross-site scripting (XSS) attack or the theft of data through a
phishing attack.
XSS using timed document navigations (CVE-2013-0793)" [9]
MFSA 2013-39: "Mozilla community member Tobias Schula reported that
if gfx.color_management.enablev4 preference is enabled manually in
about:config, some grayscale PNG images will be rendered incorrectly
and cause memory corruption during PNG decoding when certain color
profiles are in use. A crafted PNG image could use this flaw to leak
data through rendered images drawing from random memory. By default,
this preference is not enabled.
some grayscale PNG images display improperly when
"gfx.color_management.enablev4" is enabled (CVE-2013-0792)" [10]
MFSA 2013-40: "Mozilla community member Ambroz Bizjak reported an
out-of-bounds array read in the CERT_DecodeCertPackage function of
the Network Security Services (NSS) libary when decoding a
certificate. When this occurs, it will lead to memory corruption and
a non-exploitable crash.
CERT_DecodeCertPackage reads bytes outside the input buffer
(CVE-2013-0791)" [11]
MITIGATION
It is recommended that users update to the latest versions of
Mozilla Firefox, Firefox ESR, Thunderbird, Thunderbird ESR and
SeaMonkey to correct these issues.
