vulnerabilities :

  - Multiple remote code execution vulnerabilities exist in
    Microsoft Office due to improper handling of objects in
    memory. An unauthenticated, remote attacker can exploit
    these, by convincing a user to open a specially crafted
    document, to execute arbitrary code in the context of
    the current user. (CVE-2017-8509, CVE-2017-8511,
    CVE-2017-8512)

  - A remote code execution vulnerability exists in
    Microsoft PowerPoint due to improper handling of objects
    in memory. An unauthenticated, remote attacker can
    exploit this, by convincing a user to open a specially
    crafted file, to execute arbitrary code in the context
    of the current user. (CVE-2017-8513)

  - A reflective cross-site scripting (XSS) vulnerability
    exists in Microsoft SharePoint Server due improper
    validation of user-supplied input in web requests. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted request, to execute arbitrary script
    code in a user's browser session. (CVE-2017-8514)

  - An elevation of privilege vulnerability exists when
    Microsoft SharePoint Server does not properly sanitize 
    a specially crafted web request to an affected
    SharePoint server. An authenticated attacker could
    exploit the vulnerability by sending a specially crafted
    request to an affected SharePoint server. (CVE-2017-8551)");

vulnerabilities :

  - Multiple remote code execution vulnerabilities exist in
    Microsoft Office due to improper validation of input
    before loading dynamic link library (DLL) files. An
    unauthenticated, remote attacker can exploit these, by
    convincing a user to open a specially crafted Office
    document, to execute arbitrary code in the context of
    the current user. (CVE-2017-0260. CVE-2017-8506)

  - Multiple information disclosure vulnerabilities exist in
    Windows Uniscribe due to improper handling of objects in
    memory. An unauthenticated, remote attacker can exploit
    these, by convincing a user to visit a specially crafted
    website or to open a specially crafted document file, to
    disclose the contents of memory. (CVE-2017-0282,
    CVE-2017-0284, CVE-2017-0285, CVE-2017-8534)

  - Multiple remote code execution vulnerabilities exist in
    Windows Uniscribe due to improper handling of objects in
    memory. An unauthenticated, remote attacker can exploit
    these, by convincing a user to visit a specially crafted
    website or open a specially crafted document, to execute
    arbitrary code in the context of the current user.
    (CVE-2017-0283, CVE-2017-8528)

  - Multiple information disclosure vulnerabilities exist in
    the Windows GDI component due to improper handling of
    objects in memory. An unauthenticated, remote attacker
    can exploit these, by convincing a user to visit a
    specially crafted website or to open a specially crafted
    document file, to disclose the contents of memory.
    (CVE-2017-0286, CVE-2017-0287, CVE-2017-0288,
    CVE-2017-0289, CVE-2017-8531, CVE-2017-8532,
    CVE-2017-8533)

  - A remote code execution vulnerability exists in
    Microsoft Windows due to improper parsing of PDF files.
    An unauthenticated, remote attacker can exploit this, by
    convincing a user to open a specially crafted PDF file,
    to execute arbitrary code in the context of the current
    user. (CVE-2017-0292)

  - A remote code execution vulnerability exists in
    Microsoft Outlook due to improper parsing of email
    messages. An unauthenticated, remote attacker can
    exploit this, by convincing a user to open a specially
    crafted email message, to execute arbitrary code in the
    context of the current user. (CVE-2017-8507)

  - A security bypass vulnerability exists in Microsoft
    Outlook due to improper parsing of file formats. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to open a specially crafted Office
    document, to bypass security feature protections.
    (CVE-2017-8508)

  - Multiple remote code execution vulnerabilities exist in
    Microsoft Office due to improper handling of objects in
    memory. An unauthenticated, remote attacker can exploit
    these, by convincing a user to open a specially crafted
    Office document, to execute arbitrary code in the

    CVE-2017-8510, CVE-2017-8511, CVE-2017-8512,
    CVE-2017-8550)

  - A remote code execution vulnerability exists in
    Microsoft PowerPoint due to improper handling of objects
    in memory. An unauthenticated, remote attacker can
    exploit this, by convincing a user to open a specially
    crafted file, to execute arbitrary code in the context
    of the current user. (CVE-2017-8513)

  - 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
