"The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :
- A remote code execution vulnerability exists when
Microsoft Office improperly loads arbitrary type
libraries. 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. (CVE-2020-0760)
- A remote code execution vulnerability exists in
Microsoft Word 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. (CVE-2020-0980)
- 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-2020-0991)
- A remote code execution vulnerability exists when the
Microsoft Office Access Connectivity Engine improperly
handles objects in memory. An attacker who successfully
exploited this vulnerability could execute arbitrary
code on a victim system. An attacker could exploit this
vulnerability by enticing a victim to open a specially
crafted file. The update addresses the vulnerability by
correcting the way the Microsoft Office Access
Connectivity Engine handles objects in memory.
(CVE-2020-0961)
- A remote code execution vulnerability exists in
Microsoft Excel 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-2020-0906, CVE-2020-0979)");
