SuSE 11.2 Security Update : Mozilla Firefox (SAT Patch Number 6763)

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


Synopsis :

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

Description :

Mozilla Firefox was updated to 10.0.7ESR release, fixing a lot of bugs
and security problems.

The following security issues have been addressed :

- 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 2012-57)

In general these flaws cannot be exploited through email
in the Thunderbird and SeaMonkey products because
scripting is disabled, but are potentially a risk in
browser or browser-like contexts in those products.

- Gary Kwong, Christian Holler, Jesse Ruderman, Steve
Fink, Bob Clary, Andrew Sutherland, and Jason Smith
reported memory safety problems and crashes that affect
Firefox 14. (CVE-2012-1971)

- Gary Kwong, Christian Holler, Jesse Ruderman, John
Schoenick, Vladimir Vukicevic and Daniel Holbert
reported memory safety problems and crashes that affect
Firefox ESR 10 and Firefox 14. (CVE-2012-1970)

- Security researcher Abhishek Arya (Inferno) of Google
Chrome Security Team discovered a series of
use-after-free issues using the Address Sanitizer tool.
Many of these issues are potentially exploitable,
allowing for remote code execution. (MFSA 2012-58)

- Heap-use-after-free in
nsHTMLEditor::CollapseAdjacentTextNodes. (CVE-2012-1972)

- Heap-use-after-free in
nsObjectLoadingContent::LoadObject. (CVE-2012-1973)

- Heap-use-after-free in gfxTextRun::CanBreakLineBefore.
(CVE-2012-1974)

- Heap-use-after-free in PresShell::CompleteMove.
(CVE-2012-1975)

- Heap-use-after-free in
nsHTMLSelectElement::SubmitNamesValues. (CVE-2012-1976)

- Heap-use-after-free in
MediaStreamGraphThreadRunnable::Run(). (CVE-2012-3956)

- Heap-buffer-overflow in nsBlockFrame::MarkLineDirty.
(CVE-2012-3957)

- Heap-use-after-free in
nsHTMLEditRules::DeleteNonTableElements. (CVE-2012-3958)

- Heap-use-after-free in nsRangeUpdater::SelAdjDeleteNode.
(CVE-2012-3959)

- Heap-use-after-free in
mozSpellChecker::SetCurrentDictionary. (CVE-2012-3960)

- Heap-use-after-free in RangeData::~RangeData.
(CVE-2012-3961)

- Bad iterator in text runs. (CVE-2012-3962)

- use after free in js::gc::MapAllocToTraceKind.
(CVE-2012-3963)

- Heap-use-after-free READ 8 in gfxTextRun::GetUserData.
(CVE-2012-3964)

- Security researcher Mariusz Mlynski reported that it is
possible to shadow the location object using
Object.defineProperty. This could be used to confuse the
current location to plugins, allowing for possible
cross-site scripting (XSS) attacks. (MFSA 2012-59 /
CVE-2012-1956)

- Security researcher Mariusz Mlynski reported that when a
page opens a new tab, a subsequent window can then be
opened that can be navigated to about:newtab, a chrome
privileged page. Once about:newtab is loaded, the
special context can potentially be used to escalate
privilege, allowing for arbitrary code execution on the
local system in a maliciously crafted attack. (MFSA
2012-60 / CVE-2012-3965)

- Security researcher Frederic Hoguin reported two related
issues with the decoding of bitmap (.BMP) format images
embedded in icon (.ICO) format files. When processing a
negative 'height' header value for the bitmap image, a
memory corruption can be induced, allowing an attacker
to write random memory and cause a crash. This crash may
be potentially exploitable. (MFSA 2012-61 /
CVE-2012-3966)

- Security researcher miaubiz used the Address Sanitizer
tool to discover two WebGL issues. The first issue is a
use-after-free when WebGL shaders are called after being
destroyed. The second issue exposes a problem with Mesa
drivers on Linux, leading to a potentially exploitable
crash. (MFSA 2012-62)

- use after free, webgl fragment shader deleted by
accessor. (CVE-2012-3968)

- stack scribbling with 4-byte values choosable among a
few values, when using more than 16 sampler uniforms, on
Mesa, with all drivers CVE-2012-3967

- Security researcher Arthur Gerkis used the Address
Sanitizer tool to find two issues involving Scalable
Vector Graphics (SVG) files. The first issue is a buffer
overflow in Gecko's SVG filter code when the sum of two
values is too large to be stored as a signed 32-bit
integer, causing the function to write past the end of
an array. The second issue is a use-after-free when an
element with a 'requiredFeatures' attribute is moved
between documents. In that situation, the internal
representation of the 'requiredFeatures' value could be
freed prematurely. Both issues are potentially
exploitable. (MFSA 2012-63)

- Heap-buffer-overflow in
nsSVGFEMorphologyElement::Filter. (CVE-2012-3969)

- Heap-use-after-free in nsTArray_base::Length().
(CVE-2012-3970)

- Using the Address Sanitizer tool, Mozilla security
researcher Christoph Diehl discovered two memory
corruption issues involving the Graphite 2 library used
in Mozilla products. Both of these issues can cause a
potentially exploitable crash. These problems were fixed
in the Graphite 2 library, which has been updated for
Mozilla products. (MFSA 2012-64 / CVE-2012-3971)

- Security research Nicolas Gregoire used the Address
Sanitizer tool to discover an out-of-bounds read in the
format-number feature of XSLT, which can cause
inaccurate formatting of numbers and information
leakage. This is not directly exploitable. (MFSA 2012-65
/ CVE-2012-3972)

- Mozilla security researcher Mark Goodwin discovered an
issue with the Firefox developer tools' debugger. If
remote debugging is disabled, but the experimental
HTTPMonitor extension has been installed and enabled, a
remote user can connect to and use the remote debugging
service through the port used by HTTPMonitor. A
remote-enabled flag has been added to resolve this
problem and close the port unless debugging is
explicitly enabled. (MFSA 2012-66 / CVE-2012-3973)

- Security researcher Masato Kinugawa reported that if a
crafted executable is placed in the root partition on a
Windows file system, the Firefox and Thunderbird
installer will launch this program after a standard
installation instead of Firefox or Thunderbird, running
this program with the user's privileges. (MFSA 2012-67 /
CVE-2012-3974)

- Security researcher vsemozhetbyt reported that when the
DOMParser is used to parse text/html data in a Firefox
extension, linked resources within this HTML data will
be loaded. If the data being parsed in the extension is
untrusted, it could lead to information leakage and can
potentially be combined with other attacks to become
exploitable. (MFSA 2012-68 / CVE-2012-3975)

- Security researcher Mark Poticha reported an issue where
incorrect SSL certificate information can be displayed
on the addressbar, showing the SSL data for a previous
site while another has been loaded. This is caused by
two onLocationChange events being fired out of the
expected order, leading to the displayed certificate
data to not be updated. This can be used for phishing
attacks by allowing the user to input form or other data
on a newer, attacking, site while the credentials of an
older site appear on the addressbar. (MFSA 2012-69 /
CVE-2012-3976)

- Mozilla security researcher moz_bug_r_a4 reported that
certain security checks in the location object can be
bypassed if chrome code is called content in a specific
manner. This allowed for the loading of restricted
content. This can be combined with other issues to
become potentially exploitable. (MFSA 2012-70 /
CVE-2012-3978)

- Mozilla developer Blake Kaplan reported that
__android_log_print is called insecurely in places. If a
malicious web page used a dump() statement with a
specially crafted string, it can trigger a potentially
exploitable crash. (MFSA 2012-71 / CVE-2012-3979)

This vulnerability only affects Firefox for Android.

- Security researcher Colby Russell discovered that eval
in the web console can execute injected code with chrome
privileges, leading to the running of malicious code in
a privileged context. This allows for arbitrary code
execution through a malicious web page if the web
console is invoked by the user. (MFSA 2012-72 /
CVE-2012-3980)
