Synopsis :

The Microsoft Excel Products are affected by multiple vulnerabilities.

Description :

The Microsoft Excel 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-2017-8631, CVE-2017-8632)
