Security update for Mozilla Firefox (important)

MozillaFirefox has been updated to the 17.0.5ESR release
fixing bugs and security issues.

Also Mozilla NSS has been updated to version 3.14.3 and
Mozilla NSPR to 4.9.6.

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. (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.
(CVE-2013-0789)

Jim Chen reported a memory safety problem that
affects Firefox for Android

(CVE-2013-0790)

MFSA 2013-31 / CVE-2013-0800: 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.

MFSA 2013-32 / CVE-2013-0799: Security researcher
Frederic 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.

MFSA 2013-33 / CVE-2013-0798: 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.

This vulnerability only affects Firefox for Android.

MFSA 2013-34 / CVE-2013-0797: 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.

MFSA 2013-35 / CVE-2013-0796: 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.

MFSA 2013-36 / CVE-2013-0795: 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.

MFSA 2013-37 / CVE-2013-0794: 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.

MFSA 2013-38 / CVE-2013-079: 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.

MFSA 2013-39 / CVE-2013-0792: 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.

MFSA 2013-40 / CVE-2013-0791: 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.
