SuSE 11 / 11.1 Security Update : Mozilla Firefox (SAT Patch Numbers 3159 / 3160)

This script is Copyright (C) 2010-2013 Tenable Network Security, Inc.


Synopsis :

The remote SuSE 11 host is missing one or more security updates.

Description :

Mozilla Firefox 3.6 was updated to version 3.6.10, fixing various bugs
and security issues.

The following security issues were 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 2010-49 / CVE-2010-3169)

- Security researcher Chris Rohlf of Matasano Security
reported that the implementation of the HTML frameset
element contained an integer overflow vulnerability. The
code responsible for parsing the frameset columns used
an 8-byte counter for the column numbers, so when a very
large number of columns was passed in the counter would
overflow. When this counter was subsequently used to
allocate memory for the frameset, the memory buffer
would be too small, potentially resulting in a heap
buffer overflow and execution of attacker-controlled
memory. (MFSA 2010-50 / CVE-2010-2765)

- Security researcher Sergey Glazunov reported a dangling
pointer vulnerability in the implementation of
navigator.plugins in which the navigator object could
retain a pointer to the plugins array even after it had
been destroyed. An attacker could potentially use this
issue to crash the browser and run arbitrary code on a
victim's computer. (MFSA 2010-51 / CVE-2010-2767)

- Security researcher Haifei Li of FortiGuard Labs
reported that Firefox could be used to load a malicious
code library that had been planted on a victim's
computer. Firefox attempts to load dwmapi.dll upon
startup as part of its platform detection, so on systems
that don't have this library, such as Windows XP,
Firefox will subsequently attempt to load the library
from the current working directory. An attacker could
use this vulnerability to trick a user into downloading
a HTML file and a malicious copy of dwmapi.dll into the
same directory on their computer and opening the HTML
file with Firefox, thus causing the malicious code to be
executed. If the attacker was on the same network as the
victim, the malicious DLL could also be loaded via a UNC
path. The attack also requires that Firefox not
currently be running when it is asked to open the HTML
file and accompanying DLL. As this is a Windows only
problem, it does not affect the Linux version. It is
listed for completeness only. (MFSA 2010-52 /
CVE-2010-3131)

- Security researcher wushi of team509 reported a heap
buffer overflow in code routines responsible for
transforming text runs. A page could be constructed with
a bidirectional text run which upon reflow could result
in an incorrect length being calculated for the run of
text. When this value is subsequently used to allocate
memory for the text too small a buffer may be created
potentially resulting in a buffer overflow and the
execution of attacker controlled memory. (MFSA 2010-53 /
CVE-2010-3166)

- Security researcher regenrecht reported via
TippingPoint's Zero Day Initiative that there was a
remaining dangling pointer issue leftover from the fix
to CVE-2010-2753. Under certain circumstances one of the
pointers held by a XUL tree selection could be freed and
then later reused, potentially resulting in the
execution of attacker-controlled memory. (MFSA 2010-54 /
CVE-2010-2760)

- Security researcher regenrecht reported via
TippingPoint's Zero Day Initiative that XUL objects
could be manipulated such that the setting of certain
properties on the object would trigger the removal of
the tree from the DOM and cause certain sections of
deleted memory to be accessed. In products based on
Gecko version 1.9.2 (Firefox 3.6, Thunderbird 3.1) and
newer this memory has been overwritten by a value that
will cause an unexploitable crash. In products based on
Gecko version 1.9.1 (Firefox 3.5, Thunderbird 3.0, and
SeaMonkey 2.0) and older an attacker could potentially
use this vulnerability to crash a victim's browser and
run arbitrary code on their computer. (MFSA 2010-55 /
CVE-2010-3168)

- Security researcher regenrecht reported via
TippingPoint's Zero Day Initiative that the
implementation of XUL 's content view contains a
dangling pointer vulnerability. One of the content
view's methods for accessing the internal structure of
the tree could be manipulated into removing a node prior
to accessing it, resulting in the accessing of deleted
memory. If an attacker can control the contents of the
deleted memory prior to its access they could use this
vulnerability to run arbitrary code on a victim's
machine. (MFSA 2010-56 / CVE-2010-3167)

- Security researcher regenrecht reported via
TippingPoint's Zero Day Initiative that code used to
normalize a document contained a logical flaw that could
be leveraged to run arbitrary code. When the
normalization code ran, a static count of the document's
child nodes was used in the traversal, so a page could
be constructed that would remove DOM nodes during this
normalization which could lead to the accessing of a
deleted object and potentially the execution of
attacker-controlled memory. (MFSA 2010-57 /
CVE-2010-2766)

- Security researcher Marc Schoenefeld reported that a
specially crafted font could be applied to a document
and cause a crash on Mac systems. The crash showed signs
of memory corruption and presumably could be used by an
attacker to execute arbitrary code on a victim's
computer. This issue probably does not affect the Linux
builds and so is listed for completeness. (MFSA 2010-58
/ CVE-2010-2770)

- Mozilla developer Blake Kaplan reported that the wrapper
class XPCSafeJSObjectWrapper (SJOW), a security wrapper
that allows content-defined objects to be safely
accessed by privileged code, creates scope chains ending
in outer objects. Users of SJOWs which expect the scope
chain to end on an inner object may be handed a chrome
privileged object which could be leveraged to run
arbitrary JavaScript with chrome privileges. Michal
Zalewski's recent contributions helped to identify this
architectural weakness. (MFSA 2010-59 / CVE-2010-2762)

- Mozilla security researcher mozbugr_a4 reported that the
wrapper class XPCSafeJSObjectWrapper (SJOW) on the
Mozilla 1.9.1 development branch has a logical error in
its scripted function implementation that allows the
caller to run the function within the context of another
site. This is a violation of the same-origin policy and
could be used to mount an XSS attack. (MFSA 2010-60 /
CVE-2010-2763)

- Security researchers David Huang and Collin Jackson of
Carnegie Mellon University CyLab (Silicon Valley campus)
reported that the type attribute of an tag can override
the charset of a framed HTML document, even when the
document is included across origins. A page could be
constructed containing such an tag which sets the
charset of the framed document to UTF-7. This could
potentially allow an attacker to inject UTF-7 encoded
JavaScript into a site, bypassing the site's XSS
filters, and then executing the code using the above
technique. (MFSA 2010-61 / CVE-2010-2768)

- Security researcher Paul Stone reported that when an
HTML selection containing JavaScript is copy-and-pasted
or dropped onto a document with designMode enabled the
JavaScript will be executed within the context of the
site where the code was dropped. A malicious site could
leverage this issue in an XSS attack by persuading a
user into taking such an action and in the process
running malicious JavaScript within the context of
another site. (MFSA 2010-62 / CVE-2010-2769)

- Matt Haggard reported that the statusText property of an
XMLHttpRequest object is readable by the requestor even
when the request is made across origins. This status
information reveals the presence of a web server and
could be used to gather information about servers on
internal private networks. This issue was also
independently reported to Mozilla by Nicholas Berthaume.
