Google Chrome Releases reports :

36 security fixes in this release

Please reference CVE/URL list for details

The remote host is affected by the vulnerability described in GLSA-201612-11 (Chromium: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in the Chromium web       browser. Please review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, cause a Denial of Service condition, obtain       sensitive information, or bypass security restrictions.
  Workaround :

    There is no known workaround at this time.

The version of Google Chrome installed on the remote macOS or Mac OS X host is prior to 55.0.2883.75. It is, therefore, affected by the following vulnerabilities :

  - A use-after-free error exists in PDFium in the     Document::removeField() function within file     fpdfsdk/javascript/Document.cpp when removing fields     within a document. An unauthenticated, remote attacker     can exploit this to dereference already freed memory,     resulting in the execution of arbitrary code.
    (CVE-2016-5203)

  - A universal cross-site scripting (XSS) vulnerability     exists in Blink due to improper handling of the 'use'     SVG element when calling event listeners on a cloned     node. An unauthenticated, remote attacker can exploit     this to execute arbitrary script code in a user's     browser session. (CVE-2016-5204)

  - A universal cross-site scripting (XSS) vulnerability     exists in Blink due to permitting frame swaps during     frame detach. An unauthenticated, remote attacker can     exploit this to execute arbitrary script code in a     user's browser session. (CVE-2016-5205)

  - A security bypass vulnerability exists in PDFium due to     a flaw in the DocumentLoader::GetRequest() function     within file pdf/document_loader.cc when handling     redirects in the plugin. An unauthenticated, remote     attacker can exploit this to bypass the same-origin     policy. (CVE-2016-5206)

  - A universal cross-site scripting (XSS) vulnerability     exists in Blink, specifically in the     V8EventListener::getListenerFunction() function within     file bindings/core/v8/V8EventListener.cpp, due to     allowing the 'handleEvent' getter to run on forbidden     scripts. An unauthenticated, remote attacker can exploit     this to execute arbitrary script code in a user's     browser session. (CVE-2016-5207)

  - A universal cross-site scripting (XSS) vulnerability     exists in Blink due to improper handling of triggered     events (e.g., closing a color chooser for an input     element). An unauthenticated, remote attacker can     exploit this to execute arbitrary script code in a     user's browser session. (CVE-2016-5208)

  - An out-of-bounds write error exists in Blink due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     execute arbitrary code. (CVE-2016-5209)

  - An out-of-bounds write error exists in PDFium in the     CWeightTable::GetPixelWeightSize() function within file     core/fxge/dib/fx_dib_engine.cpp. An unauthenticated,     remote attacker can exploit this to corrupt memory,     resulting in a denial of service condition or the     execution of arbitrary code. (CVE-2016-5210)

  - An unspecified use-after-free error exists in PDFium due     to improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     corrupt memory, resulting in a denial of service     condition or the execution of arbitrary code.
    (CVE-2016-5211)

  - A unspecified flaw exists in the DevTools component due     to improper validation of certain URLs that allows an     unauthenticated, remote attacker to disclose the content     of arbitrary files. (CVE-2016-5212)

  - Multiple use-after-free errors exist in the inspector     component in V8 that allow an unauthenticated, remote     attacker to execute arbitrary code. (CVE-2016-5213,     CVE-2016-5219)

  - A file download protection bypass vulnerability exists     when downloading files that involve 'data:' URIs,     unknown URI schemes, or overly long URLs. An     unauthenticated, remote attacker can exploit this to     cause a file to be downloaded without applying the     mark-of-the-web. (CVE-2016-5214)

  - A use-after-free error exists in WebAudio within file     content/renderer/media/renderer_webaudiodevice_impl.cc     due to improper handling of web audio. An     unauthenticated, remote attacker can exploit this to     dereference already freed memory, resulting in the     execution of arbitrary code. (CVE-2016-5215)

  - A use-after-free error exists in PDFium, specifically     within file pdf/pdfium/pdfium_engine.cc, due to improper     handling of non-visible page unloading. An     unauthenticated, remote attacker can exploit this to     dereference already freed memory, resulting in the     execution of arbitrary code. (CVE-2016-5216)

  - A flaw exists in PDFium due to the use of unvalidated     data by the PDF helper extension. An authenticated,     remote attacker can exploit this to have an unspecified     impact. No other details are available. (CVE-2016-5217)

  - A flaw exists when handling chrome.tabs API navigations     and displaying the pending URL. An unauthenticated,     remote attacker can exploit this to spoof the Omnibox     address. (CVE-2016-5218)

  - An information disclosure vulnerability exists in     PDFium, due to improper handling of 'file: navigation',     that allows an unauthenticated, remote attacker to     disclose local files. (CVE-2016-5220)

  - An integer overflow condition exists in ANGLE due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     have an unspecified impact. (CVE-2016-5221)

  - A flaw exists in the NavigatorImpl::NavigateToEntry()     function within file frame_host/navigator_impl.cc due to     improper handling of invalid URLs. An unauthenticated,     remote attacker can exploit this to spoof the Omnibox     address. (CVE-2016-5222)

  - An integer overflow condition exists in PDFium within     file core/fpdfapi/page/cpdf_page.cpp that allows an     authenticated, remote attacker to have an unspecified     impact. No other details are available. (CVE-2016-5223)

  - A security bypass vulnerability exists in the SVG     component due to denorm handling not being disabled     before calling Skia filter code. An unauthenticated,     remote attacker can exploit this to bypass the     same-origin policy. (CVE-2016-5224)

  - A flaw exists in Blink, specifically in the     HTMLFormElement::scheduleFormSubmission() function     within file html/HTMLFormElement.cpp, due to improper     enforcement of the form-action CSP (Content Security     Policy). An unauthenticated, remote attacker can exploit     this to bypass intended access restrictions.
    (CVE-2016-5225)

  - A cross-site scripting (XSS) vulnerability exists in     Blink within file ui/views/tabs/tab_strip.cc due to     improper validation of input when dropping JavaScript     URLs on a tab. An unauthenticated, remote attacker can     exploit this to execute arbitrary script code in a     user's browser session. (CVE-2016-5226)

  - An unspecified flaw exists that allows an     unauthenticated, remote attacker to disclose Content     Security Policy (CSP) referrers. (CVE-2016-9650)

  - An unspecified flaw exists in V8 within lookup.cc that     allows unauthorized private property access. An     unauthenticated, remote attacker can exploit this to     execute arbitrary code. (CVE-2016-9651)

  - Multiple other vulnerabilities exist, the most serious     of which can be exploited by an authenticated, remote     attacker to execute arbitrary code. (CVE-2016-9652)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

  - A cross-site scripting (XSS) vulnerability exists in     Blink within file ui/views/tabs/tab_strip.cc due to     improper validation of input when dropping JavaScript     URLs on a tab. An unauthenticated, remote attacker can     exploit this to execute arbitrary script code in a     user's browser session. (CVE-2016-5226)

  - An unspecified flaw exists that allows an     unauthenticated, remote attacker to disclose Content     Security Policy (CSP) referrers. (CVE-2016-9650)

  - An unspecified flaw exists in V8 within lookup.cc that     allows unauthorized private property access. An     unauthenticated, remote attacker can exploit this to     execute arbitrary code. (CVE-2016-9651)

  - Multiple other vulnerabilities exist, the most serious     of which can be exploited by an authenticated, remote     attacker to execute arbitrary code. (CVE-2016-9652)
