Summary

A remote code execution vulnerability exists in Microsoft PowerPoint 2007 Service Pack 3, Microsoft PowerPoint 2010 Service Pack 2, Microsoft PowerPoint 2013 Service Pack 1, Microsoft PowerPoint 2013 RT Service Pack 1, Microsoft PowerPoint 2016, Microsoft PowerPoint Viewer 2007, Microsoft SharePoint Server 2013 Service Pack 1, Microsoft SharePoint Enterprise Server 2016, Microsoft Office Web Apps 2010 Service Pack 2, and Microsoft Office Compatibility Pack Service Pack 3 when they fail to properly handle objects in memory, aka "PowerPoint Remote Code Execution Vulnerability". This CVE ID is unique from CVE-2017-8743.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionThe Microsoft Powerpoint Products are missing security updates. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists in Microsoft Office software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file. Note that the Preview Pane is not an attack vector for this vulnerability. The security update addresses the vulnerability by correcting how Office handles objects in memory.

    descriptionThe Microsoft Office Products are missing security updates. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists in Microsoft Office software when it fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. For example, the file could then take actions on behalf of the logged-on user with the same permissions as the current user. Exploitation of this vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file. The security update addresses the vulnerability by correcting how Microsoft Office handles files in memory. (CVE-2017-8630, CVE-2017-8744) - A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. There are multiple ways an attacker could exploit this vulnerability. In a web- based attack scenario, an attacker could host a specially crafted website that is designed to exploit this vulnerability and then convince a user to view the website. An attacker would have no way to force users to view the attacker-controlled content.

        correcting how Microsoft Office handles files in memory.
        (CVE-2017-8630, CVE-2017-8744)
    
      - A remote code execution vulnerability exists when the
        Windows font library improperly handles specially
        crafted embedded fonts. An attacker who successfully
        exploited this vulnerability could take control of the
        affected system. An attacker could then install
        programs; view, change, or delete data; or create new
        accounts with full user rights. Users whose accounts are
        configured to have fewer user rights on the system could
        be less impacted than users who operate with
        administrative user rights. There are multiple ways an
        attacker could exploit this vulnerability. In a web-
        based attack scenario, an attacker could host a
        specially crafted website that is designed to exploit
        this vulnerability and then convince a user to view the
        website. An attacker would have no way to force users to
        view the attacker-controlled content. Instead, an
        attacker would have to convince users to take action,
        typically by getting them to click a link in an email
        message or in an Instant Messenger message that takes
        users to the attacker's website, or by opening an
        attachment sent through email. In a file sharing attack
        scenario, an attacker could provide a specially crafted
        document file that is designed to exploit this
        vulnerability, and then convince a user to open the
        document file. The security update addresses the
        vulnerabilities by correcting how the Windows font
        library handles embedded fonts. (CVE-2017-8682)
    
      - An information disclosure vulnerability exists when
        Windows Uniscribe improperly discloses the contents of
        its memory. An attacker who successfully exploited the
        vulnerability could obtain information to further
        compromise the users system. There are multiple ways an
        attacker could exploit the vulnerability, such as by
        convincing a user to open a specially crafted document
        or by convincing a user to visit an untrusted webpage.
        The update addresses the vulnerability by correcting how
        Windows Uniscribe handles objects in memory.
        (CVE-2017-8695)
    
      - A remote code execution vulnerability exists due to the
        way Windows Uniscribe handles objects in memory. An
        attacker who successfully exploited this vulnerability
        could take control of the affected system. An attacker
        could then install programs; view, change, or delete
        data; or create new accounts with full user rights.
        Users whose accounts are configured to have fewer user
        rights on the system could be less impacted than users
        who operate with administrative user rights. There are
        multiple ways an attacker could exploit this
        vulnerability: In a web-based attack scenario, an
        attacker could host a specially crafted website designed
        to exploit this vulnerability and then convince a user
        to view the website. An attacker would have no way to
        force users to view the attacker-controlled content.
        Instead, an attacker would have to convince users to
        take action, typically by getting them to click a link
        in an email or instant message that takes users to the
        attacker's website, or by opening an attachment sent
        through email. In a file-sharing attack scenario, an

        a user to open the document file.The security update
        addresses the vulnerability by correcting how Windows
        Uniscribe handles objects in memory. (CVE-2017-8696)
    
      - A remote code execution vulnerability exists in
        Microsoft Office software when the software fails to
        properly handle objects in memory. An attacker who
        successfully exploited the vulnerability could run
        arbitrary code in the context of the current user. If
        the current user is logged on with administrative user
        rights, an attacker could take control of the affected
        system. An attacker could then install programs; view,
        change, or delete data; or create new accounts with full
        user rights. Users whose accounts are configured to have
        fewer user rights on the system could be less impacted
        than users who operate with administrative user rights.
        Exploitation of the vulnerability requires that a user
        open a specially crafted file with an affected version
        of Microsoft Office software. In an email attack
        scenario, an attacker could exploit the vulnerability by
        sending the specially crafted file to the user and
        convincing the user to open the file. In a web-based
        attack scenario, an attacker could host a website (or
        leverage a compromised website that accepts or hosts
        user-provided content) that contains a specially crafted
        file designed to exploit the vulnerability. An attacker
        would have no way to force users to visit the website.
        Instead, an attacker would have to convince users to
        click a link, typically by way of an enticement in an
        email or instant message, and then convince them to open
        the specially crafted file. Note that the Preview Pane
        is not an attack vector for this vulnerability. The
        security update addresses the vulnerability by
        correcting how Office handles objects in memory.
        (CVE-2017-8742)
    
      - An information disclosure vulnerability exists in the
        way that the Windows Graphics Device Interface (GDI)
        handles objects in memory, allowing an attacker to
        retrieve information from a targeted system. By itself,
        the information disclosure does not allow arbitrary code
        execution; however, it could allow arbitrary code to be
        run if the attacker uses it in combination with another
        vulnerability. To exploit this vulnerability, an
        attacker would have to log on to an affected system and
        run a specially crafted application. Note that where the
        severity is indicated as Critical in the Affected
        Products table, the Preview Pane is an attack vector for
        this vulnerability. The security update addresses the
        vulnerability by correcting how GDI handles memory
        addresses. (CVE-2017-8676)");

        attacker who successfully exploited this vulnerability
        could take control of the affected system. An attacker

        compromised website that accepts or hosts user-provided
        content) that contains a specially crafted file that is
        designed to exploit the vulnerability. However, an
        attacker would have no way to force the user to visit
        the website. Instead, an attacker would have to convince
        the user to click a link, typically by way of an
        enticement in an email or Instant Messenger message, and
        then convince the user to open the specially crafted
        file. The security update addresses the vulnerability by
        correcting how Microsoft Office handles files in memory.
        (CVE-2017-8631, CVE-2017-8632)
    
      - A remote code execution vulnerability exists in
        Microsoft Office software when the software fails to
        properly handle objects in memory. An attacker who
        successfully exploited the vulnerability could run
        arbitrary code in the context of the current user. If
        the current user is logged on with administrative user
        rights, an attacker could take control of the affected
        system. An attacker could then install programs; view,
        change, or delete data; or create new accounts with full
        user rights. Users whose accounts are configured to have
        fewer user rights on the system could be less impacted
        than users who operate with administrative user rights.
        Exploitation of the vulnerability requires that a user
        open a specially crafted file with an affected version
        of Microsoft Office software. In an email attack
        scenario, an attacker could exploit the vulnerability by
        sending the specially crafted file to the user and
        convincing the user to open the file. In a web-based
        attack scenario, an attacker could host a website (or
        leverage a compromised website that accepts or hosts
        user-provided content) that contains a specially crafted
        file designed to exploit the vulnerability. An attacker
        would have no way to force users to visit the website.
        Instead, an attacker would have to convince users to
        click a link, typically by way of an enticement in an
        email or instant message, and then convince them to open
        the specially crafted file. Note that the Preview Pane
        is not an attack vector for this vulnerability. The
        security update addresses the vulnerability by
        correcting how Office handles objects in memory.

        (CVE-2017-8631)
    
      - A remote code execution vulnerability exists when the
        Windows font library improperly handles specially
        crafted embedded fonts. An attacker who successfully
        exploited this vulnerability could take control of the
        affected system. An attacker could then install
        programs; view, change, or delete data; or create new
        accounts with full user rights. Users whose accounts are
        configured to have fewer user rights on the system could
        be less impacted than users who operate with
        administrative user rights. There are multiple ways an
        attacker could exploit this vulnerability. In a web-
        based attack scenario, an attacker could host a
        specially crafted website that is designed to exploit
        this vulnerability and then convince a user to view the
        website. An attacker would have no way to force users to
        view the attacker-controlled content. Instead, an
        attacker would have to convince users to take action,
        typically by getting them to click a link in an email
        message or in an Instant Messenger message that takes
        users to the attacker's website, or by opening an
        attachment sent through email. In a file sharing attack
        scenario, an attacker could provide a specially crafted
        document file that is designed to exploit this
        vulnerability, and then convince a user to open the
        document file. The security update addresses the
        vulnerabilities by correcting how the Windows font
        library handles embedded fonts. (CVE-2017-8682)
    
      - An information disclosure vulnerability exists when
        Windows Uniscribe improperly discloses the contents of
        its memory. An attacker who successfully exploited the
        vulnerability could obtain information to further
        compromise the users system. There are multiple ways an
        attacker could exploit the vulnerability, such as by
        convincing a user to open a specially crafted document
        or by convincing a user to visit an untrusted webpage.
        The update addresses the vulnerability by correcting how
        Windows Uniscribe handles objects in memory.
        (CVE-2017-8695)
    
      - A remote code execution vulnerability exists due to the
        way Windows Uniscribe handles objects in memory. An
        attacker who successfully exploited this vulnerability
        could take control of the affected system. An attacker
        could then install programs; view, change, or delete
        data; or create new accounts with full user rights.
        Users whose accounts are configured to have fewer user
        rights on the system could be less impacted than users
        who operate with administrative user rights. There are
        multiple ways an attacker could exploit this
        vulnerability: In a web-based attack scenario, an
        attacker could host a specially crafted website designed
        to exploit this vulnerability and then convince a user
        to view the website. An attacker would have no way to

        Instead, an attacker would have to convince users to
        take action, typically by getting them to click a link
        in an email or instant message that takes users to the
        attacker's website, or by opening an attachment sent
        through email. In a file-sharing attack scenario, an

        user rights. Users whose accounts are configured to have
        fewer user rights on the system could be less impacted
        than users who operate with administrative user rights.
        Exploitation of the vulnerability requires that a user
        open a specially crafted file with an affected version
        of Microsoft Office software. In an email attack
        scenario, an attacker could exploit the vulnerability by
        sending the specially crafted file to the user and
        convincing the user to open the file. In a web-based
        attack scenario, an attacker could host a website (or
        leverage a compromised website that accepts or hosts
        user-provided content) that contains a specially crafted
        file designed to exploit the vulnerability. An attacker
        would have no way to force users to visit the website.
        Instead, an attacker would have to convince users to
        click a link, typically by way of an enticement in an
        email or instant message, and then convince them to open
        the specially crafted file. Note that the Preview Pane
        is not an attack vector for this vulnerability. The
        security update addresses the vulnerability by
        correcting how Office handles objects in memory.
        (CVE-2017-8742)
    
      - An information disclosure vulnerability exists in the
        way that the Windows Graphics Device Interface (GDI)
        handles objects in memory, allowing an attacker to
        retrieve information from a targeted system. By itself,
        the information disclosure does not allow arbitrary code
        execution; however, it could allow arbitrary code to be
        run if the attacker uses it in combination with another
        vulnerability. To exploit this vulnerability, an
        attacker would have to log on to an affected system and
        run a specially crafted application. Note that where the
        severity is indicated as Critical in the Affected
        Products table, the Preview Pane is an attack vector for
        this vulnerability. The security update addresses the
        vulnerability by correcting how GDI handles memory
        addresses. (CVE-2017-8676)");
