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)

Versions of Mozilla Firefox prior to 49.0 are unpatched for the following vulnerabilities :

 - A flaw exists as the certificate pinning policy for built-in sites like 'addons.mozilla.org' is not honored due to the pins having expired. This may allow a Man-in-the-Middle (MitM) attacker able to generate a trusted certificate to conduct spoofing attacks.
 - A flaw exists in the 'CrossCompartmentWrapper::getPrototypeIfOrdinary()' function in 'js/src/proxy/CrossCompartmentWrapper.cpp' that is triggered as certain input is not properly validated. With a specially crafted web page, a context-dependent attacker can corrupt memory and potentially execute arbitrary code.
 - A use-after-free error exists in 'dom/media/systemservices/LoadManager.h' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
 - A flaw exists in the 'imgFrame::InitForDecoder()' function in 'image/imgFrame.cpp' that is triggered when handling paletted images. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - An unspecified flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists in the 'GenerateCallGetter()' function in 'jit/IonCaches.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - An unspecified flaw exists in 'dom/media/platforms/wmf/WMFVideoMFTManager.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists in 'netwerk/sctp/src/netinet/sctputil.c' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists in the WebRTC component that is triggered as certain input is not properly validated when handling H.264 STAP-A content. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists in the 'nsNodeUtils::CloneAndAdopt()' function in 'dom/base/nsNodeUtils.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists in the 'parse()' function in 'libavcodec/vp9_parser.c' that is triggered when handling input frame sizes. This may allow a context-dependent attacker to corrupt memory, crashing a process linked against the library and potentially allowing the execution of arbitrary code.
 - An unspecified flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists in 'netwerk/sctp/src/netinet/sctputil.c' that is triggered when handling association failures. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists in the 'nsHttpChannelAuthProvider::OnAuthCancelled()' function in 'netwerk/protocol/http/nsHttpChannelAuthProvider.cpp' that is triggered as certain input is not properly validated.
