"The Microsoft Office application, Office Web Apps, or SharePoint
Server installed on the remote Windows host is missing a security
update. It is, therefore, affected by multiple vulnerabilities :

  - An arbitrary code execution vulnerability exists in
    Microsoft Outlook due to improper parsing of email
    messages. An unauthenticated, remote attacker can
    exploit this, via a specially crafted email message, to
    execute arbitrary code. (CVE-2017-0106)

  - An information disclosure vulnerability exists in
    Microsoft Office due to improper handling of objects in
    memory. An unauthenticated, remote attacker can exploit
    this, by convincing a user to open a specially crafted
    Excel file, to disclose the contents of memory.
    (CVE-2017-0194)

  - A cross-site scripting (XSS) vulnerability exists in
    Office Web Apps Server due to improper validation of
    input before returning it to users. An authenticated,
    remote attacker can exploit this, via a specially
    crafted request, to execute arbitrary script code in a
    user's browser session. (CVE-2017-0195)

  - An arbitrary code execution vulnerability exists in
    Microsoft Office due to improper validation of input
    before loading dynamic link library (DLL) files. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to open a specially crafted Office
    document, to execute arbitrary code. (CVE-2017-0197)

  - An arbitrary code execution vulnerability exists in
    Microsoft Office and Windows WordPad due to improper
    validation of user-supplied input. An unauthenticated,
    remote attacker can exploit this, by convincing a user
    to open a specially crafted file, to execute arbitrary
    code. Note that this vulnerability is being utilized to
    spread the Petya ransomware. (CVE-2017-0199)

  - A security feature bypass vulnerability exists in
    Microsoft Office due to improper parsing of file
    formats. An unauthenticated, remote attacker can exploit
    this, by convincing a user into opening a specially
    crafted file, to bypass security features.
    (CVE-2017-0204)

  - A spoofing vulnerability in Microsoft Outlook due to
    improper validation of input passed via HTML tags. An
    unauthenticated, remote attacker can exploit this, by
    sending an email with specific HTML tags, to display a
    malicious authentication prompt and gain access to a
    user's authentication information or login credentials.
    (CVE-2017-0207)

  - An unspecified flaw exists in Microsoft Office in the
    Encapsulated PostScript (EPS) filter that allows an
    attacker to have an unspecified impact. (CVE-2017-2605)");

is missing security updates. It is, therefore, affected by
multiple vulnerabilities :

  - A remote code execution vulnerability exists in the
    way that Microsoft Outlook parses specially crafted
    email messages. An attacker who successfully exploited
    the vulnerability could take control of an affected
    system to then install programs; view, change, or
    delete data; or create new accounts with full user
    rights. (CVE-2017-0106)

  - A security feature bypass vulnerability exists in
    Microsoft Office software when it improperly handles the
    parsing of file formats. To exploit the vulnerability,
    an attacker would have to convince a user to open a
    specially crafted file. (CVE-2017-0204)

  - A remote code execution vulnerability exists when
    Microsoft Office improperly validates input before
    loading dynamic link library (DLL) files. An attacker
    who successfully exploited this vulnerability could take
    control of an affected system to then install programs;
    view, change, or delete data; or create new accounts
    with full user rights. (CVE-2017-8506)

  - A remote code execution vulnerability exists in the way
    that Microsoft Outlook parses specially crafted email
    messages. An attacker who successfully exploited this
    vulnerability could take control of an affected system.
   (CVE-2017-8507)

  - A security feature bypass vulnerability exists in
    Microsoft Office software when it improperly handles the
    parsing of file formats. (CVE-2017-8508)

  - A security feature bypass vulnerability exists when
    Microsoft Office Outlook improperly handles input.
    An attacker who successfully exploited the vulnerability
    could execute arbitrary commands. (CVE-2017-8571)

  - An information disclosure vulnerability exists when
    Microsoft Outlook fails to properly validate
    authentication requests. (CVE-2017-8572)

  - A remote code execution vulnerability exists in the way
    that Microsoft Outlook parses specially crafted email
    messages. An attacker who successfully exploited the
