sdkp3-MozillaFirefoxSecurity update for Mozilla Firefox
This update brings Mozilla Firefox to version 3.5.15, fixing various bugs
and security issues.
The following security issues were fixed:
*
MFSA 2010-49 / CVE-2010-3169: 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 2010-50 / CVE-2010-2765: 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 2010-51 / CVE-2010-2767: 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 2010-52 / CVE-2010-3131: 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 2010-53 / CVE-2010-3166: 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 2010-54 / CVE-2010-2760: 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 2010-55 / CVE-2010-3168: 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 2010-56 / CVE-2010-3167: 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 2010-57 / CVE-2010-2766: 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 2010-58 / CVE-2010-2770: 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 2010-59 / CVE-2010-2762: 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 2010-60 / CVE-2010-2763: 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 2010-61 / CVE-2010-2768: 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 2010-62 / CVE-2010-2769: 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 2010-63 / CVE-2010-2764: 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.
*
MFSA 2010-64: 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. References

MFSA 2010-65 / CVE-2010-3179: Security researcher Alexander Miller
reported that passing an excessively long string to document.write
could cause text rendering routines to end up in an inconsistent
state with sections of stack memory being overwritten with the string
data. An attacker could use this flaw to crash a victim's browser and
potentially run arbitrary code on their computer.
*
MFSA 2010-66 / CVE-2010-3180: Security researcher Sergey Glazunov
reported that it was possible to access the locationbar property of a
window object after it had been closed. Since the closed window's
memory could have been subsequently reused by the system it was
possible that an attempt to access the locationbar property could
result in the execution of attacker-controlled memory.
*
MFSA 2010-67 / CVE-2010-3183: Security researcher regenrecht reported
via TippingPoint's Zero Day Initiative that when
window.__lookupGetter__ is called with no arguments the code assumes
the top JavaScript stack value is a property name. Since there were
no arguments passed into the function, the top value could represent
uninitialized memory or a pointer to a previously freed JavaScript
object. Under such circumstances the value is passed to another
subroutine which calls through the dangling pointer, potentially
executing attacker-controlled memory.
*
MFSA 2010-68 / CVE-2010-3177: Google security researcher Robert
Swiecki reported that functions used by the Gopher parser to convert
text to HTML tags could be exploited to turn text into executable
JavaScript. If an attacker could create a file or directory on a
Gopher server with the encoded script as part of its name the script
would then run in a victim's browser within the context of the site.
*
MFSA 2010-69 / CVE-2010-3178: Security researcher Eduardo Vela Nava
reported that if a web page opened a new window and used a
javascript: URL to make a modal call, such as alert(), then
subsequently navigated the page to a different domain, once the modal
call returned the opener of the window could get access to objects in
the navigated window. This is a violation of the same-origin policy
and could be used by an attacker to steal information from another
web site.
*
MFSA 2010-70 / CVE-2010-3170: Security researcher Richard Moore
reported that when an SSL certificate was created with a common name
containing a wildcard followed by a partial IP address a valid SSL
connection could be established with a server whose IP address
matched the wildcard range by browsing directly to the IP address. It
is extremely unlikely that such a certificate would be issued by a
Certificate Authority.
*
MFSA 2010-71 / CVE-2010-3182: Dmitri Gribenko reported that the
script used to launch Mozilla applications on Linux was effectively
including the current working directory in the LD_LIBRARY_PATH
environment variable. If an attacker was able to place into the
current working directory a malicious shared library with the same
name as a library that the bootstrapping script depends on the
attacker could have their library loaded instead of the legitimate
library.
