The version of Firefox installed on the remote Windows host is prior to 37.0. It is, therefore, affected by the following vulnerabilities :

  - A privilege escalation vulnerability exists which     relates to anchor navigation. A remote attacker can     exploit this to bypass same-origin policy protections,     allowing a possible execution of arbitrary scripts in a     privileged context. Note that this is a variant of     CVE-2015-0818 that was fixed in Firefox 36.0.4.
    (CVE-2015-0801)

  - Access to certain privileged internal methods is     retained when navigating from windows created to contain     privileged UI content to unprivileged pages. An attacker     can exploit this to execute arbitrary JavaScript with     elevated privileges. (CVE-2015-0802)

  - Multiple type confusion issues exist that can lead to     use-after-free errors, which a remote attacker can     exploit to execute arbitrary code or cause a denial of     service. (CVE-2015-0803, CVE-2015-0804)

  - Multiple memory corruption issues exist related to Off     Main Thread Compositing when rendering 2D graphics,     which a remote attacker can exploit to execute arbitrary     code or cause a denial of service. (CVE-2015-0805,     CVE-2015-0806)

  - A cross-site request forgery (XSRF) vulnerability exists     in the sendBeacon() function due to cross-origin     resource sharing (CORS) requests following 30x     redirections. (CVE-2015-0807)

  - An issue exists in WebRTC related to memory management     for simple-style arrays, which may be used by a remote     attacker to cause a denial of service. (CVE-2015-0808)

  - An out-of-bounds read issue exists in the QCMS color     management library that could lead to an information     disclosure. (CVE-2015-0811)

  - An issue exists that can allow a man-in-the-middle     attacker to bypass user-confirmation and install a     Firefox lightweight theme by spoofing a Mozilla     sub-domain. (CVE-2015-0812)   
  - Multiple memory safety issues exist within the browser     engine. A remote attacker can exploit these to corrupt     memory and possibly execute arbitrary code.
    (CVE-2015-0814, CVE-2015-0815)

  - A privilege escalation vulnerability exists related to     documents loaded through a 'resource:' URL. An attacker     can exploit this to load pages and execute JavaScript     with elevated privileges. (CVE-2015-0816)

The remote host is affected by the vulnerability described in GLSA-201512-10 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox and       Mozilla Thunderbird. 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.
  Workaround :

    There is no known workaround at this time.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2550-1 advisory.

    Olli Pettay and Boris Zbarsky discovered an issue during anchor navigations in some circumstances. If a     user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to     bypass same-origin policy restrictions. (CVE-2015-0801)

    Bobby Holley discovered that windows created to hold privileged UI content retained access to privileged     internal methods if navigated to unprivileged content. An attacker could potentially exploit this in     combination with another flaw, in order to execute arbitrary script in a privileged context.
    (CVE-2015-0802)

    Several type confusion issues were discovered in Firefox. If a user were tricked in to opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service via application     crash, or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2015-0803,     CVE-2015-0804)

    Abhishek Arya discovered memory corruption issues during 2D graphics rendering. If a user were tricked in     to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of     service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox.
    (CVE-2015-0805, CVE-2015-0806)

    Christoph Kerschbaumer discovered that CORS requests from navigator.sendBeacon() followed 30x redirections     after preflight. If a user were tricked in to opening a specially crafted website, an attacker could     potentially exploit this to conduct cross-site request forgery (XSRF) attacks. (CVE-2015-0807)

    Mitchell Harper discovered an issue with memory management of simple-type arrays in WebRTC. An attacker     could potentially exploit this to cause undefined behaviour. (CVE-2015-0808)

    Felix Grbert discovered an out-of-bounds read in the QCMS colour management library. If a user were     tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain     sensitive information. (CVE-2015-0811)

    Armin Razmdjou discovered that lightweight themes could be installed in Firefox without a user approval     message, from Mozilla subdomains over HTTP without SSL. A remote attacker could potentially exploit this     by conducting a Machine-In-The-Middle (MITM) attack to install themes without user approval.
    (CVE-2015-0812)

    Aki Helin discovered a use-after-free when playing MP3 audio files using the Fluendo MP3 GStreamer plugin     in certain circumstances. If a user were tricked in to opening a specially crafted website, an attacker     could potentially exploit this to cause a denial of service via application crash, or execute arbitrary     code with the privileges of the user invoking Firefox. (CVE-2015-0813)

    Christian Holler, Andrew McCreight, Gary Kwong, Karl Tomlinson, Randell Jesup, Shu-yu Guo, Steve Fink,     Tooru Fujisawa, and Byron Campen discovered multiple memory safety issues in Firefox. If a user were     tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a     denial of service via application crash, or execute arbitrary code with the privileges of the user     invoking Firefox. (CVE-2015-0814, CVE-2015-0815)

    Mariusz Mlynski discovered that documents loaded via resource: URLs (such as PDF.js) could load privileged     chrome pages. If a user were tricked in to opening a specially crafted website, an attacker could     potentially exploit this in combination with another flaw, in order to execute arbitrary script in a     privileged context. (CVE-2015-0816)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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