It is, therefore, affected by the following 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. (CVE-2018-0794, CVE-2018-0795)
- An Office RTF remote code execution vulnerability exists
in Microsoft Office software when the Office software
fails to properly handle RTF files. 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. (CVE-2018-0797)
- 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

CVE-2018-0806, CVE-2018-0807, CVE-2018-0812)
- 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.
An attacker could then install programs; view, change,
or delete data; or create new accounts with full user
rights. Exploitation of this vulnerability requires that
a user open a specially crafted file with an affected
version of Microsoft Outlook. (CVE-2018-0793)");
