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 version of Firefox installed on the remote Mac OS X host is prior to 39.0. It is, therefore, affected by multiple vulnerabilities :

  - A security downgrade vulnerability exists due to a flaw     in Network Security Services (NSS). When a client allows     for a ECDHE_ECDSA exchange, but the server does not send     a ServerKeyExchange message, the NSS client will take     the EC key from the ECDSA certificate. A remote attacker     can exploit this to silently downgrade the exchange to a     non-forward secret mixed-ECDH exchange. (CVE-2015-2721)

  - Multiple user-after-free errors exist when using an     XMLHttpRequest object in concert with either shared or     dedicated workers. A remote attacker can exploit this     to cause a denial of service condition. (CVE-2015-2722,     CVE-2015-2733)

  - Multiple memory corruption issues exist that allow an     attacker to cause a denial of service condition or     potentially execute arbitrary code. (CVE-2015-2724,     CVE-2015-2725)

  - A security bypass vulnerability exists due to a failure     to preserve context restrictions. A remote attacker can     exploit this, via a crafted web site that is accessed     with unspecified mouse and keyboard actions, to read     arbitrary files or execute arbitrary JavaScript code.
    (CVE-2015-2727)

  - A type confusion flaw exists in the Indexed Database     Manager's handling of IDBDatabase. A remote attacker can     exploit this to cause a denial of service condition or     to execute arbitrary code. (CVE-2015-2728)

  - An out-of-bounds read flaw exists in the     AudioParamTimeline::AudioNodeInputValue() function when     computing oscillator rending ranges. An attacker can     exploit this to disclose the contents of four bytes of     memory or cause a denial of service condition.
    (CVE-2015-2729)

  - A signature spoofing vulnerability exists due to a flaw     in Network Security Services (NSS) in its Elliptic Curve     Digital Signature Algorithm (ECDSA) signature     validation. A remote attacker can exploit this to forge     signatures. (CVE-2015-2730)

  - A use-after-free error exists in the     CSPService::ShouldLoad() function when modifying the     Document Object Model to remove a DOM object. An     attacker can exploit this to dereference already freed     memory, potentially resulting in the execution of     arbitrary code. (CVE-2015-2731)

  - An uninitialized memory use issue exists in the     CairoTextureClientD3D9::BorrowDrawTarget() function, the     ::d3d11::SetBufferData() function, and the     YCbCrImageDataDeserializer::ToDataSourceSurface()     function. The impact is unspecified. (CVE-2015-2734,     CVE-2015-2737, CVE-2015-2738)

  - A memory corruption issue exists in the     nsZipArchive::GetDataOffset() function due to improper     string length checks. An attacker can exploit this, via     a crafted ZIP archive, to potentially execute arbitrary     code. (CVE-2015-2735)

  - A memory corruption issue exists in the     nsZipArchive::BuildFileList() function due to improper     validation of user-supplied input. An attacker can     exploit this, via a crafted ZIP archive, to potentially     execute arbitrary code. (CVE-2015-2736)

  - An unspecified memory corruption issue exists in the     ArrayBufferBuilder::append() function due to improper     validation of user-supplied input. An attacker can     exploit this to potentially execute arbitrary code.
    (CVE-2015-2739)

  - A buffer overflow condition exists in the     nsXMLHttpRequest::AppendToResponseText() function due to     improper validation of user-supplied input. An attacker     can exploit this to potentially execute arbitrary code.
    (CVE-2015-2740)

  - A security bypass vulnerability exists due to a flaw in     certificate pinning checks. Key pinning is not enforced     upon encountering an X.509 certificate problem that     generates a user dialog. A man-in-the-middle attacker     can exploit this to bypass intended access restrictions.
    (CVE-2015-2741)

  - An information disclosure vulnerability exists due to     crash reports containing key press information.
    (CVE-2015-2742)

  - A privilege escalation vulnerability exists in the PDF     viewer (PDF.js) due to internal workers being executed     insecurely. An attacker can exploit this, by leveraging     a Same Origin Policy bypass, to execute arbitrary code.
    (CVE-2015-2743)

  - A man-in-the-middle vulnerability, known as Logjam,     exists due to a flaw in the SSL/TLS protocol. A remote     attacker can exploit this flaw to downgrade connections     using ephemeral Diffie-Hellman key exchange to 512-bit     export-grade cryptography. (CVE-2015-4000)
