An update that fixes 18 vulnerabilities is now available.
Mozilla XULRunner was updated to 14.0.1, fixing bugs and
Following security issues were fixed: MFSA 2012-42: 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.
CVE-2012-1949: Brian Smith, Gary Kwong, Christian Holler,
Jesse Ruderman, Christoph Diehl, Chris Jones, Brad Lassey,
and Kyle Huey reported memory safety problems and crashes
that affect Firefox 13.
CVE-2012-1948: Benoit Jacob, Jesse Ruderman, Christian
Holler, and Bill McCloskey reported memory safety problems
and crashes that affect Firefox ESR 10 and Firefox 13.
MFSA 2012-43 / CVE-2012-1950: Security researcher Mario
Gomes andresearch firm Code Audit Labs reported a mechanism
to short-circuit page loads through drag and drop to the
addressbar by canceling the page load. This causes the
address of the previously site entered to be displayed in
the addressbar instead of the currently loaded page. This
could lead to potential phishing attacks on users.
Google security researcher Abhishek Arya used the Address
Sanitizer tool to uncover four issues: two use-after-free
problems, one out of bounds read bug, and a bad cast. The
first use-after-free problem is caused when an array of
nsSMILTimeValueSpec objects is destroyed but attempts are
made to call into objects in this array later. The second
use-after-free problem is in nsDocument::AdoptNode when it
adopts into an empty document and then adopts into another
document, emptying the first one. The heap buffer overflow
is in ElementAnimations when data is read off of end of an
array and then pointers are dereferenced. The bad cast
happens when nsTableFrame::InsertFrames is called with
frames in aFrameList that are a mix of row group frames and
column group frames. AppendFrames is not able to handle
All four of these issues are potentially exploitable.

Heap-use-after-free in nsDocument::AdoptNode CVE-2012-1953:
Out of bounds read in ElementAnimations::EnsureStyleRuleFor
CVE-2012-1952: Bad cast in nsTableFrame::InsertFrames
MFSA 2012-45 / CVE-2012-1955: Security researcher Mariusz
Mlynski reported an issue with spoofing of the location
property. In this issue, calls to history.forward and
history.back are used to navigate to a site while
displaying the previous site in the addressbar but changing
the baseURI to the newer site. This can be used for
phishing by allowing the user input form or other data on
the newer, attacking, site while appearing to be on the
older, displayed site.
MFSA 2012-46 / CVE-2012-1966: Mozilla security researcher
moz_bug_r_a4 reported a cross-site scripting (XSS) attack
through the context menu using a data: URL. In this issue,
context menu functionality ("View Image", "Show only this
frame", and "View background image") are disallowed in a
XSS. This can lead to arbitrary code execution.
MFSA 2012-47 / CVE-2012-1957: Security researcher Mario
HTML feed-view using tag within the RSS . This problem is
due to tags not being filtered out during parsing and can
lead to a potential cross-site scripting (XSS) attack. The
flaw existed in a parser utility class and could affect
other parts of the browser or add-ons which rely on that
class to sanitize untrusted input.
MFSA 2012-48 / CVE-2012-1958: Security researcher Arthur
Gerkis used the Address Sanitizer tool to find a
use-after-free in nsGlobalWindow::PageHidden when
mFocusedContent is released and oldFocusedContent is used
afterwards. This use-after-free could possibly allow for
remote code execution.
MFSA 2012-49 / CVE-2012-1959: Mozilla developer Bobby
Holley found that same-compartment security wrappers (SCSW)
can be bypassed by passing them to another compartment.
Cross-compartment wrappers often do not go through SCSW,
but have a filtering policy built into them. When an object
is wrapped cross-compartment, the SCSW is stripped off and,
when the object is read read back, it is not known that
SCSW was previously present, resulting in a bypassing of
SCSW. This could result in untrusted content having access
to the XBL that implements browser functionality.
MFSA 2012-50 / CVE-2012-1960: Google developer Tony Payne
reported an out of bounds (OOB) read in QCMS, Mozillaâs
color management library. With a carefully crafted color
profile portions of a user's memory could be incorporated
into a transformed image and possibly deciphered.
MFSA 2012-51 / CVE-2012-1961: Bugzilla developer FrÃ©dÃ©ric
Buclin reported that the "X-Frame-Options header is ignored
when the value is duplicated, for example X-Frame-Options:
SAMEORIGIN, SAMEORIGIN. This duplication occurs for unknown
reasons on some websites and when it occurs results in
Mozilla browsers not being protected against possible
clickjacking attacks on those pages.
MFSA 2012-52 / CVE-2012-1962: Security researcher Bill
Keese reported a memory corruption. This is caused by
JSDependentString::undepend changing a dependent string
into a fixed string when there are additional dependent
strings relying on the same base. When the undepend occurs
during conversion, the base data is freed, leaving other
dependent strings with dangling pointers. This can lead to
a potentially exploitable crash.
MFSA 2012-53 / CVE-2012-1963: Security researcher
Karthikeyan Bhargavan of Prosecco at INRIA reported Content
Security Policy (CSP) 1.0 implementation errors. CSP
violation reports generated by Firefox and sent to the
"report-uri" location include sensitive data within the
"blocked-uri" parameter. These include fragment components
and query strings even if the "blocked-uri" parameter has a
different origin than the protected resource. This can be
used to retrieve a user's OAuth 2.0 access tokens and
OpenID credentials by malicious sites.
MFSA 2012-54 / CVE-2012-1964: Security Researcher Matt
McCutchen reported that a clickjacking attack using the
certificate warning page. A man-in-the-middle (MITM)
attacker can use an iframe to display its own certificate
error warning page (about:certerror) with the "Add
Exception" button of a real warning page from a malicious
site. This can mislead users to adding a certificate
exception for a different site than the perceived one. This
can lead to compromised communications with the user
perceived site through the MITM attack once the certificate
exception has been added.
MFSA 2012-55 / CVE-2012-1965: Security researchers Mario
Gomes and Soroush Dalili reported that since Mozilla allows
the pseudo-protocol feed: to prefix any valid URL, it is
execute scripts in some contexts. On some sites it may be
possible to use this to evade output filtering that would
cross-site scripting (XSS) problems on these sites.
MFSA 2012-56 / CVE-2012-1967: Mozilla security researcher
moz_bug_r_a4 reported a arbitrary code execution attack
add-ons to safely execute script in the context of a web
such a sandbox with insufficient context that can allow
those scripts to escape from the sandbox and run with
elevated privilege. This can lead to arbitrary code
