SuSE 10 Security Update : Mozilla Firefox (ZYPP Patch Number 8226)

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote SuSE 10 host is missing a security-related patch.

Description :

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 :

- 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. (MFSA 2012-42)

- Benoit Jacob, Jesse Ruderman, Christian Holler, and Bill
McCloskey reported memory safety problems and crashes
that affect Firefox ESR 10 and Firefox 13.
(CVE-2012-1948)

- 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
2012-43 / CVE-2012-1950)

- 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. (MFSA 2012-44)

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

- 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 2012-45 / CVE-2012-1955)

- 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 2012-46 /
CVE-2012-1966)

- 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 2012-47 /
CVE-2012-1957)

- 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 2012-48 / CVE-2012-1958)

- 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 2012-49 / CVE-2012-1959)

- 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 deciphered. (MFSA 2012-50 /
CVE-2012-1960)

- 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 2012-51 /
CVE-2012-1961)

- 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
2012-52 / CVE-2012-1962)

- 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 2012-53 / CVE-2012-1963)

- 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 2012-54 / CVE-2012-1964)

- 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 2012-55 / CVE-2012-1965)

- 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 execution. (MFSA 2012-56
/ CVE-2012-1967)
