  - A same-origin policy bypass vulnerability exists in     Microsoft Edge due to a failure to properly apply the     Same Origin Policy for HTML elements. An     unauthenticated, remote attacker can exploit this, by     convincing a user to follow a link, to load a page with     malicious content. (CVE-2017-8523)

  - A remote code execution vulnerability exists in the     Windows font library due to improper handling of     embedded fonts. An unauthenticated, remote attacker can     exploit this, by convincing a user to visit a specially     crafted website or open a specially crafted Microsoft     document, to execute arbitrary code in the context of     the current user. (CVE-2017-8527)

  - A same-origin policy bypass vulnerability exists in     Microsoft Edge due to a failure to properly enforce     same-origin policies. An unauthenticated, remote     attacker can exploit this, by convincing a user to visit     a specially crafted website, to disclose information     from origins outside the current one. (CVE-2017-8530)

  - A remote code execution vulnerability exists in the     Windows Search functionality due to improper handling of     objects in memory. An unauthenticated, remote attacker     can exploit this, via a specially crafted SMB message,     to execute arbitrary code. (CVE-2017-8543)

  - An information disclosure vulnerability exists in the     Windows Search functionality due to improper handling of     objects in memory. An unauthenticated, remote attacker     can exploit this, via a specially crafted SMB message,     to disclose sensitive information. (CVE-2017-8544)

  - A remote code execution vulnerability exists in Internet     Explorer due to improper handling of objects in memory.
    An unauthenticated, remote attacker can exploit this, by     convincing a user to visit a specially crafted website,     to execute arbitrary code in the context of the current     user. (CVE-2017-8547)

  - A remote code execution vulnerability exists in     Microsoft Edge in the JavaScript scripting engine due to     improper handling of objects in memory. An     unauthenticated, remote attacker can exploit this, by     convincing a user to visit a specially crafted website,     to execute arbitrary code in the context of the current     user. (CVE-2017-8549)

  - An information disclosure vulnerability exists in the     Windows Graphics component due to improper handling of     objects in memory. An authenticated, remote attacker can     exploit this, via a specially crafted application, to     disclose sensitive information. (CVE-2017-8575)

  - An elevation of privilege vulnerability exists in the     Windows Graphics component due to improper     initialization of objects in memory. A local attacker     can exploit this, via a specially crafted application,     to execute arbitrary code in kernel mode.
    (CVE-2017-8576)

  - An elevation of privilege vulnerability exists DirectX     due to improper handling of objects in memory. A local     attacker can exploit this, via a specially crafted     application, to execute arbitrary code in kernel mode.
    (CVE-2017-8576)

  - An information disclosure vulnerability exists in the     Windows kernel due to improper handling of objects in     memory. An authenticated, remote attacker can exploit     this, via a specially crafted application, to disclose     the contents of memory. (CVE-2017-8554)
