"The version of Mozilla Firefox installed on the remote Windows host
is prior to 49.0. It is, therefore, affected by multiple
vulnerabilities :

  - An out-of-bounds read error exists within file
    dom/security/nsCSPParser.cpp when handling content
    security policies (CSP) containing empty referrer
    directives. An unauthenticated, remote attacker can
    exploit this to cause a denial of service condition.
    (CVE-2016-2827)

  - Multiple memory safety issues exist that allow an
    unauthenticated, remote attacker to potentially execute
    arbitrary code. (CVE-2016-5256, CVE-2016-5257)

  - A heap buffer overflow condition exists in the
    nsCaseTransformTextRunFactory::TransformString()
    function in layout/generic/nsTextRunTransformations.cpp
    when converting text containing certain Unicode
    characters. An unauthenticated, remote attacker can
    exploit this to execute arbitrary code. (CVE-2016-5270)

  - An out-of-bounds read error exists in the
    nsCSSFrameConstructor::GetInsertionPrevSibling()
    function in file layout/base/nsCSSFrameConstructor.cpp
    when handling text runs. An unauthenticated, remote
    attacker can exploit this to disclose memory contents.
    (CVE-2016-5271)

  - A type confusion error exists within file
    layout/forms/nsRangeFrame.cpp when handling layout with
    input elements. An unauthenticated, remote attacker can
    exploit this to execute arbitrary code. (CVE-2016-5272)

  - An unspecified flaw exists in the
    HyperTextAccessible::GetChildOffset() function that
    allows an unauthenticated, remote attacker to execute
    arbitrary code. (CVE-2016-5273)

  - A use-after-free error exists within file
    layout/style/nsRuleNode.cpp when handling web animations
    during restyling. An unauthenticated, remote attacker
    can exploit this to execute arbitrary code.
    (CVE-2016-5274)

  - A buffer overflow condition exists in the
    FilterSupport::ComputeSourceNeededRegions() function
    when handling empty filters during canvas rendering. An
    unauthenticated, remote attacker can exploit this to
    execute arbitrary code. (CVE-2016-5275)

  - A use-after-free error exists in the
    DocAccessible::ProcessInvalidationList() function within
    file accessible/generic/DocAccessible.cpp when setting
    an aria-owns attribute. An unauthenticated, remote
    attacker can exploit this to execute arbitrary code.
    (CVE-2016-5276)

  - A use-after-free error exists in the
    nsRefreshDriver::Tick() function when handling web
    animations destroying a timeline. An unauthenticated,
    remote attacker can exploit this to execute arbitrary
    code. (CVE-2016-5277)

  - A buffer overflow condition exists in the
    nsBMPEncoder::AddImageFrame() function within file
    dom/base/ImageEncoder.cpp when encoding image frames to
    images. An unauthenticated, remote attacker can exploit
    this to execute arbitrary code. (CVE-2016-5278)

  - A flaw exists that is triggered when handling
    drag-and-drop events for files. An unauthenticated,
    remote attacker can exploit this disclose the full local
    file path. (CVE-2016-5279)

  - A use-after-free error exists in the
    nsTextNodeDirectionalityMap::RemoveElementFromMap()
    function within file dom/base/DirectionalityUtils.cpp
    when handling changing of text direction. An
    unauthenticated, remote attacker can exploit this to
    execute arbitrary code. (CVE-2016-5280)

  - A use-after-free error exists when handling SVG format
    content that is being manipulated through script code.
    An unauthenticated, remote attacker can exploit this to
    execute arbitrary code. (CVE-2016-5281)

  - A flaw exists when handling content that requests
    favicons from non-whitelisted schemes that are using
    certain URI handlers. An unauthenticated, remote
    attacker can exploit this to bypass intended
    restrictions. (CVE-2016-5282)

  - A flaw exists that is related to the handling of iframes
    that allow an unauthenticated, remote attacker to
    conduct an 'iframe src' fragment timing attack,
    resulting in disclosure of cross-origin data.
    (CVE-2016-5283)

  - A flaw exists due to the certificate pinning policy for
    built-in sites (e.g., addons.mozilla.org) not being
    honored when pins have expired. A man-in-the-middle
    (MitM) attacker can exploit this to generate a trusted
    certificate, which could be used to conduct spoofing
    attacks. (CVE-2016-5284)");
