The version of Firefox installed on the remote Windows host is prior to 3.5. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2009-34 advisory.

  - The JavaScript engine in Mozilla Firefox before 3.0.12 and Thunderbird allows remote attackers to cause a     denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors     related to (1) nsDOMClassInfo.cpp, (2) JS_HashTableRawLookup, and (3) MirrorWrappedNativeParent and     js_LockGCThingRT. (CVE-2009-2466)

  - Mozilla Firefox before 3.0.12 and Thunderbird allow remote attackers to cause a denial of service (memory     corruption and application crash) or execute arbitrary code via vectors involving double frame     construction, related to (1) nsHTMLContentSink.cpp, (2) nsXMLContentSink.cpp, and (3) nsPresShell.cpp, and     the nsSubDocumentFrame::Reflow function. (CVE-2009-2465)

  - The browser engine in Mozilla Firefox before 3.0.12 and Thunderbird allows remote attackers to cause a     denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors     related to (1) the frame chain and synchronous events, (2) a SetMayHaveFrame assertion and     nsCSSFrameConstructor::CreateFloatingLetterFrame, (3) nsCSSFrameConstructor::ConstructFrame, (4) the child     list and initial reflow, (5) GetLastSpecialSibling, (6) nsFrameManager::GetPrimaryFrameFor and MathML, (7)     nsFrame::GetBoxAscent, (8) nsCSSFrameConstructor::AdjustParentFrame, (9) nsDOMOfflineResourceList, and     (10) nsContentUtils::ComparePosition. (CVE-2009-2462)

  - Multiple integer overflows in the (1) PL_Base64Decode and (2) PL_Base64Encode functions in     nsprpub/lib/libc/src/base64.c in Mozilla Firefox before 3.0.12, Thunderbird before 2.0.0.24, and SeaMonkey     before 1.1.19 allow remote attackers to cause a denial of service (memory corruption and application     crash) or possibly execute arbitrary code via unspecified vectors that trigger buffer overflows.
    (CVE-2009-2463)

  - The nsXULTemplateQueryProcessorRDF::CheckIsSeparator function in Mozilla Firefox before 3.0.12, SeaMonkey     2.0a1pre, and Thunderbird allows remote attackers to cause a denial of service (memory corruption and     application crash) or possibly execute arbitrary code via vectors related to loading multiple RDF files in     a XUL tree element. (CVE-2009-2464)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several flaws were discovered in the Firefox browser and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program.
(CVE-2009-2462, CVE-2009-2463, CVE-2009-2464, CVE-2009-2465, CVE-2009-2466, CVE-2009-2469)

Attila Suszter discovered a flaw in the way Firefox processed Flash content. If a user were tricked into viewing and navigating within a specially crafted Flash object, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-2467)

It was discovered that Firefox did not properly handle some SVG content. An attacker could exploit this to cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-2469)

A flaw was discovered in the JavaScript engine. If a user were tricked into viewing a malicious website, an attacker could exploit this perform cross-site scripting attacks. (CVE-2009-2472).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The MozillaFirefox 3.0.12 release fixes various bugs and some critical security issues.

MFSA 2009-34 / CVE-2009-2462 / CVE-2009-2463 / CVE-2009-2464 / CVE-2009-2465 / CVE-2009-2466: Mozilla developers and community members identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these crashes 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 2009-35 / CVE-2009-2467: Security researcher Attila Suszter reported that when a page contains a Flash object which presents a slow script dialog, and the page is navigated while the dialog is still visible to the user, the Flash plugin is unloaded resulting in a crash due to a call to the deleted object. This crash could potentially be used by an attacker to run arbitrary code on a victim's computer.

MFSA 2009-36 / CVE-2009-1194: oCERT security researcher Will Drewry reported a series of heap and integer overflow vulnerabilities which independently affected multiple font glyph rendering libraries. On Linux platforms libpango was susceptible to the vulnerabilities while on OS X CoreGraphics was similarly vulnerable. An attacker could trigger these overflows by constructing a very large text run for the browser to display. Such an overflow can result in a crash which the attacker could potentially use to run arbitrary code on a victim's computer. The open-source nature of Linux meant that Mozilla was able to work with the libpango maintainers to implement the correct fix in version 1.24 of that system library which was distributed with OS security updates. On Mac OS X Firefox works around the CoreGraphics flaw by limiting the length of text runs passed to the system.

MFSA 2009-37 / CVE-2009-2469: Security researcher PenPal reported a crash involving a SVG element on which a watch function and
__defineSetter__ function have been set for a particular property. The crash showed evidence of memory corruption and could potentially be used by an attacker to run arbitrary code on a victim's computer.

MFSA 2009-39 / CVE-2009-2471: Mozilla developer Blake Kaplan reported that setTimeout, when called with certain object parameters which should be protected with a XPCNativeWrapper, will fail to keep the object wrapped when compiling the new function to be executed. If chrome privileged code were to call setTimeout using this as an argument, the this object will lose its wrapper and could be unsafely accessed by chrome code. An attacker could use such vulnerable code to run arbitrary JavaScript with chrome privileges.

MFSA 2009-40 / CVE-2009-2472: Mozilla security researcher moz_bug_r_a4 reported a series of vulnerabilities in which objects that normally receive a XPCCrossOriginWrapper are constructed without the wrapper.
This can lead to cases where JavaScript from one website may unsafely access properties of such an object which had been set by a different website. A malicious website could use this vulnerability to launch a XSS attack and run arbitrary JavaScript within the context of another site.

Several remote vulnerabilities have been discovered in Xulrunner, a runtime environment for XUL applications, such as the Iceweasel web browser. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-2462     Martijn Wargers, Arno Renevier, Jesse Ruderman, Olli     Pettay and Blake Kaplan discovered several issues in the     browser engine that could potentially lead to the     execution of arbitrary code. (MFSA 2009-34)

  - CVE-2009-2463     monarch2020 reported an integer overflow in a base64     decoding function. (MFSA 2009-34)

  - CVE-2009-2464     Christophe Charron reported a possibly exploitable crash     occurring when multiple RDF files were loaded in a XUL     tree element. (MFSA 2009-34)

  - CVE-2009-2465     Yongqian Li reported that an unsafe memory condition     could be created by specially crafted document. (MFSA     2009-34)

  - CVE-2009-2466     Peter Van der Beken, Mike Shaver, Jesse Ruderman, and     Carsten Book discovered several issues in the JavaScript     engine that could possibly lead to the execution of     arbitrary JavaScript. (MFSA 2009-34)

  - CVE-2009-2467     Attila Suszter discovered an issue related to a     specially crafted Flash object, which could be used to     run arbitrary code. (MFSA 2009-35)

  - CVE-2009-2469     PenPal discovered that it is possible to execute     arbitrary code via a specially crafted SVG element.
    (MFSA 2009-37)

  - CVE-2009-2471     Blake Kaplan discovered a flaw in the JavaScript engine     that might allow an attacker to execute arbitrary     JavaScript with chrome privileges. (MFSA 2009-39)

  - CVE-2009-2472     moz_bug_r_a4 discovered an issue in the JavaScript     engine that could be used to perform cross-site     scripting attacks. (MFSA 2009-40)

Mozilla Firefox is an open source Web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code as the user running Firefox.
(CVE-2009-2462, CVE-2009-2463, CVE-2009-2464, CVE-2009-2465, CVE-2009-2466, CVE-2009-2467, CVE-2009-2469, CVE-2009-2471)

Several flaws were found in the way Firefox handles malformed JavaScript code. A website containing malicious content could launch a cross-site scripting (XSS) attack or execute arbitrary JavaScript with the permissions of another website. (CVE-2009-2472)

The remote host is affected by the vulnerability described in GLSA-201301-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox,       Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information,       bypass restrictions and protection mechanisms, force file downloads,       conduct XML injection attacks, conduct XSS attacks, bypass the Same       Origin Policy, spoof URL&rsquo;s for phishing attacks, trigger a vertical       scroll, spoof the location bar, spoof an SSL indicator, modify the       browser&rsquo;s font, conduct clickjacking attacks, or have other unspecified       impact.
    A local attacker could gain escalated privileges, obtain sensitive       information, or replace an arbitrary downloaded file.
  Workaround :

    There is no known workaround at this time.
