MozillaFirefox 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)

    o Heap-use-after-free in     nsHTMLEditor::CollapseAdjacentTextNodes CVE-2012-1972: o     Heap-use-after-free in     nsObjectLoadingContent::LoadObject CVE-2012-1973: o     Heap-use-after-free in gfxTextRun::CanBreakLineBefore     CVE-2012-1974: o Heap-use-after-free in     PresShell::CompleteMove CVE-2012-1975 o     Heap-use-after-free in     nsHTMLSelectElement::SubmitNamesValues CVE-2012-1976: o     Heap-use-after-free in     MediaStreamGraphThreadRunnable::Run() CVE-2012-3956: o     Heap-buffer-overflow in nsBlockFrame::MarkLineDirty     CVE-2012-3957: o Heap-use-after-free in     nsHTMLEditRules::DeleteNonTableElements CVE-2012-3958: o     Heap-use-after-free in nsRangeUpdater::SelAdjDeleteNode     CVE-2012-3959: o Heap-use-after-free in     mozSpellChecker::SetCurrentDictionary CVE-2012-3960: o     Heap-use-after-free in RangeData::~RangeData     CVE-2012-3961 o Bad iterator in text runs CVE-2012-3962     o use after free in js::gc::MapAllocToTraceKind     CVE-2012-3963 o Heap-use-after-free READ 8 in     gfxTextRun::GetUserData CVE-2012-3964: * MFSA 2012-59 /     CVE-2012-1956: 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.

  - 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)

    o

    use after free, webgl fragment shader deleted by     accessor CVE-2012-3968: o

    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)

    o

    Heap-buffer-overflow in nsSVGFEMorphologyElement::Filter     CVE-2012-3969: o

    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)
