Mozilla Firefox before 35.0 and SeaMonkey before 2.32 do not consider the id-pkix-ocsp-nocheck extension in deciding whether to trust an OCSP responder, which makes it easier for remote attackers to obtain sensitive information by sniffing the network during a session in which there was an incorrect decision to accept a compromised and revoked certificate.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Mozilla Firefox before 35.0 and SeaMonkey before 2.32 do not consider the id-pkix-ocsp-nocheck extension     in deciding whether to trust an OCSP responder, which makes it easier for remote attackers to obtain     sensitive information by sniffing the network during a session in which there was an incorrect decision to     accept a compromised and revoked certificate. (CVE-2014-8642)

Note that Nessus relies on the presence of the package as reported by the vendor.

Versions of Mozilla Firefox ESR prior to 31.4 are unpatched for the following vulnerabilities : 

 - Multiple unspecified memory safety issues exist within the browser engine. (CVE-2014-8634, CVE-2014-8635)
 - A flaw exists where DOM objects with some specific properties can bypass XrayWrappers. This can allow web content to confuse privileged code, potentially enabling privilege escalation. (CVE-2014-8636)
 - A flaw exists in the rendering of bitmap images. When rending a malformed bitmap image, memory may not always be properly initialized, which can result in a leakage of data to web content. (CVE-2014-8637)
 - A flaw exists in 'navigator.sendBeacon()' in which it does not follow the cross-origin resource sharing specification. This results in requests from 'sendBeacon()' lacking an 'origin' header, which allows malicious sites to perform XSRF attacks. (CVE-2014-8638)
 - A flaw exists when receiving 407 Proxy Authentication responses with a 'set-cookie' header. This can allow a session-fixation attack. (CVE-2014-8639)
 - A flaw exists in Web Audio that can allow a small block of memory to be read. (CVE-2014-8640)
 - A read-after-free flaw exists in WebRTC due to the way tracks are handled, which can result in a potentially exploitable crash or incorrect WebRTC behavior. (CVE-2014-8641)
 - A flaw exists where delegated Online Certificate Status Protocol responder certificates fail to recognize the id-pkix-ocsp-nocheck extension. This can result in a user connecting to a site with a revoked certificate. (CVE-2014-8642)
 - A flaw exists in the Gecko Media Plugin which can allow an attacker to break out of the sandbox. (CVE-2014-8643)

The remote host is affected by the vulnerability described in GLSA-201504-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Firefox, Thunderbird,       and SeaMonkey. 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, spoof       the address bar, conduct clickjacking attacks, bypass security       restrictions and protection mechanisms,  or have other unspecified       impact.
  Workaround :

    There are no known workarounds at this time.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2458-1 advisory.

    Christian Holler, Patrick McManus, Christoph Diehl, Gary Kwong, Jesse Ruderman, Byron Campen, Terrence     Cole, and Nils Ohlmeier 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-2014-8634, CVE-2014-8635)

    Bobby Holley discovered that some DOM objects with certain properties can bypass XrayWrappers in some     circumstances. If a user were tricked in to opening a specially crafted website, an attacker could     potentially exploit this to bypass security restrictions. (CVE-2014-8636)

    Michal Zalewski discovered a use of uninitialized memory when rendering malformed bitmap images on a     canvas element. If a user were tricked in to opening a specially crafted website, an attacker could     potentially exploit this to steal confidential information. (CVE-2014-8637)

    Muneaki Nishimura discovered that requests from navigator.sendBeacon() lack an origin header. 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-2014-8638)

    Xiaofeng Zheng discovered that a web proxy returning a 407 response could inject cookies in to the     originally requested domain. If a user connected to a malicious web proxy, an attacker could potentially     exploit this to conduct session-fixation attacks. (CVE-2014-8639)

    Holger Fuhrmannek discovered a crash in Web Audio while manipulating timelines. If a user were tricked in     to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of     service. (CVE-2014-8640)

    Mitchell Harper discovered a use-after-free in WebRTC. 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-2014-8641)

    Brian Smith discovered that OCSP responses would fail to verify if signed by a delegated OCSP responder     certificate with the id-pkix-ocsp-nocheck extension, potentially allowing a user to connect to a site with     a revoked certificate. (CVE-2014-8642)

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.
