Google Chrome prior to 56.0.2924.76 for Linux, Windows and Mac, and 56.0.2924.87 for Android, failed to require a user gesture for powerful download operations, which allowed a remote attacker who convinced a user to install a malicious extension to execute arbitrary code via a crafted HTML page.

The version of Google Chrome installed on the remote macOS host is prior to 56.0.2924.76. It is, therefore, affected by multiple vulnerabilities as referenced in the 2017_01_stable-channel-update-for-desktop advisory.

  - A use after free in Google Chrome prior to 56.0.2924.76 for Linux, Windows and Mac, and 56.0.2924.87 for     Android, allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
    (CVE-2017-5019)

  - A heap buffer overflow in V8 in Google Chrome prior to 56.0.2924.76 for Linux, Windows and Mac, and     56.0.2924.87 for Android, allowed a remote attacker to potentially exploit heap corruption via a crafted     HTML page. (CVE-2017-5012)

  - Blink in Google Chrome prior to 56.0.2924.76 for Linux, Windows and Mac, and 56.0.2924.87 for Android,     incorrectly handled the sequence of events when closing a page, which allowed a remote attacker to inject     arbitrary scripts or HTML (UXSS) via a crafted HTML page. (CVE-2017-5007)

  - Blink in Google Chrome prior to 56.0.2924.76 for Linux, Windows and Mac, and 56.0.2924.87 for Android,     incorrectly handled object owner relationships, which allowed a remote attacker to inject arbitrary     scripts or HTML (UXSS) via a crafted HTML page. (CVE-2017-5006)

  - Blink in Google Chrome prior to 56.0.2924.76 for Linux, Windows and Mac, and 56.0.2924.87 for Android,     allowed attacker controlled JavaScript to be run during the invocation of a private script method, which     allowed a remote attacker to inject arbitrary scripts or HTML (UXSS) via a crafted HTML page.
    (CVE-2017-5008)

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

The remote host is affected by the vulnerability described in GLSA-201701-66 (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, bypass security restrictions, or perform       cross-site scripting (XSS).
  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 56.0.2924.76. It is, therefore, affected by the following vulnerabilities :

  - A cross-site scripting (XSS) vulnerability exists in the     Document::shutdown() function in dom/Document.cpp due to     a failure to clear the owner's widget for a frame. An     unauthenticated, remote attacker can exploit this, via a     specially crafted request, to execute arbitrary script     code in a user's browser session. (CVE-2017-5006)

  - A cross-site scripting (XSS) vulnerability exists in the     Document::shutdown() function in dom/Document.cpp due to     a failure to properly suspend pages that are closing,     but not yet fully closed. An unauthenticated, remote     attacker can exploit this, via a specially crafted     request, to execute arbitrary script code in a user's     browser session. (CVE-2017-5007)

  - A cross-site scripting (XSS) vulnerability exists in the     compileAndRunPrivateScript() function in     PrivateScriptRunner.cpp due to a failure to properly     protect private scripts. An unauthenticated, remote     attacker can exploit this, via a specially crafted     request, to execute arbitrary script code in a user's     browser session. (CVE-2017-5008)

  - An out-of-bounds read error exists in the     UsingFlexibleMode() function in decoding_state.cc due to     improper handling of frames marked as using flexible     mode. An unauthenticated, remote attacker can exploit     this to execute arbitrary code. (CVE-2017-5009)

  - A cross-site scripting (XSS) vulnerability exists in     css/FontFace.cpp due to improper handling of FontFace     objects. An unauthenticated, remote attacker can exploit     this, via a specially crafted request, to execute     arbitrary script code in a user's browser session.

  - A flaw exists in the ShouldFocusLocationBarByDefault()     function in ui/browser.cc that is triggered when     handling NTP navigations in non-selected tabs. An     unauthenticated, remote attacker can exploit this to     spoof the address. (CVE-2017-5013)

  - A heap buffer overflow condition exists in Google Skia     due to improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     execute arbitrary code. (CVE-2017-5014)

  - An unspecified flaw exists in Omnibox that allows an     unauthenticated, remote attacker to spoof the address.
    (CVE-2017-5015)

  - A flaw exists in the updateVisibleValidationMessage()     function in html/HTMLFormControlElement.cpp related to     the form validation bubble being displayed for invisible     pages. An unauthenticated, remote attacker can exploit     this to spoof the UI. (CVE-2017-5016)

  - An uninitialized memory access flaw exists in the webm     video processing implementation that allows an     unauthenticated, remote attacker to have an unspecified     impact. (CVE-2017-5017)

  - A cross-site scripting (XSS) vulnerability exists in the     App Launcher component due to a failure to properly     validate parameters. An unauthenticated, remote attacker     can exploit this, via a specially crafted request, to     execute arbitrary script code in a user's browser     session. (CVE-2017-5018)

  - A use-after-free error exists in the OnBeforeUnload()     function in render_frame_impl.cc. An unauthenticated,     remote attacker can exploit this to execute arbitrary     code. (CVE-2017-5019)

  - A cross-site scripting (XSS) vulnerability exists in     Blink due to a failure to properly validate input     related to chrome://downloads. An unauthenticated,     remote attacker can exploit this, via a specially     crafted request, to execute arbitrary script code in a     user's browser session. (CVE-2017-5020)

  - A use-after-free error exists in the Extensions     component. An unauthenticated, remote attacker can     exploit this to execute arbitrary code. (CVE-2017-5021)

  - A security bypass vulnerability exists in     frame/csp/ContentSecurityPolicy.cpp that allows an     unauthenticated, remote attacker to bypass the content     security policy (CSP). (CVE-2017-5022)

  - A type confusion flaw exists in the histogram collector     feature that is triggered when handling serialized     histograms. An unauthenticated remote attacker can     exploit this to crash the browser, resulting in a denial     of service condition. (CVE-2017-5023)

  - A heap buffer overflow condition exists in FFmpeg in the     mov_read_uuid() function in libavformat/mov.c due to     improper handling of overly long UUIDs. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-5024)

  - A heap buffer overflow condition exists in FFmpeg in the     mov_read_hdlr() function in libavformat/mov.c due to     improper validation of user-supplied input when handling     titles. An unauthenticated, remote attacker can exploit     this to execute arbitrary code. (CVE-2017-5025)

  - An unspecified flaw exists that allows an     unauthenticated, remote attacker to spoof the UI.
    (CVE-2017-5026)

  - An unspecified flaw exists in Blink that allows an     unauthenticated, remote attacker to bypass the content     security policy. (CVE-2017-5027)
