An update that fixes 18 vulnerabilities is now available.
It includes one version update.


MozillaFirefox have been updated to the 10.0.6ESR security
release fixing various bugs and several security issues,
some critical.

The ollowing security issues have been 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


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


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.


MFSA 2012-44 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-afte.r-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 this mix.

All four of these issues are potentially exploitable.

o CVE-2012-1951: Heap-use-after-free in
nsSMILTimeValueSpec::IsEventBased o CVE-2012-1954:
Heap-use-after-free in nsDocument::AdoptNode o
CVE-2012-1953: Out of bounds read in
ElementAnimations::EnsureStyleRuleFor o 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 javascript: URL but allowed in a data: URL,
allowing for XSS. This can lead to arbitrary code execution.


MFSA 2012-47 / CVE-2012-1957: Security researcher
Mario Heiderich reported that javascript could be executed
in the 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,
Mozilla's color management library. With a carefully
crafted color profile portions of a user's memory could be
incorporated into a transformed image and possibly


MFSA 2012-51 / CVE-2012-1961: Bugzilla developer
Frederic 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 possible to construct feed:javascript: URLs that will
execute scripts in some contexts. On some sites it may be
possible to use this to evade output filtering that would
otherwise strip javascript: URLs and thus contribute to
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 using a javascript: URL. The Gecko engine features a
JavaScript sandbox utility that allows the browser or
add-ons to safely execute script in the context of a web
page. In certain cases, javascript: URLs are executed in
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
