"The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :
- An information disclosure vulnerability exists when
Microsoft Office improperly discloses the contents of
its memory. An attacker who exploited the vulnerability
could use the information to compromise the users
computer or data. (CVE-2018-1007)
- An information disclosure vulnerability exists when
Office renders Rich Text Format (RTF) email messages
containing OLE objects when a message is opened or
previewed. This vulnerability could potentially result
in the disclosure of sensitive information to a
malicious site. (CVE-2018-0950)
- 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-2018-1026, CVE-2018-1030)
- A remote code execution vulnerability exists when the
Office graphics component 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. (CVE-2018-1028)");
