"The 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.
    (CVE-2017-8742, CVE-2017-8743)");
