"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 with the privileges of the user
running Firefox. (CVE-2015-2724, CVE-2015-2725, CVE-2015-2722,
CVE-2015-2727, CVE-2015-2728, CVE-2015-2729, CVE-2015-2731,

CVE-2015-2737, CVE-2015-2738, CVE-2015-2739, CVE-2015-2740)

It was found that Firefox skipped key-pinning checks when handling an
error that could be overridden by the user (for example an expired
certificate error). This flaw allowed a user to override a pinned
certificate, which is an action the user should not be able to
perform. (CVE-2015-2741)

A flaw was discovered in Mozilla's PDF.js PDF file viewer. When
combined with another vulnerability, it could allow execution of
arbitrary code with the privileges of the user running Firefox.
(CVE-2015-2743)

After installing the update, Firefox must be restarted for the changes
to take effect."

"The version of Firefox ESR installed on the remote Mac OS X host i
prior to 31.8. 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)

  - 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)

  - 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)

  - 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 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)");
