"The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :
- A remote code execution vulnerability exists when
Microsoft Office fails to properly handle certain files.
(CVE-2019-0801)
- A remote code execution vulnerability exists in the way
that Microsoft Graphics Components handle objects in
memory. An attacker who successfully exploited the
vulnerability could execute arbitrary code on a target
system. (CVE-2019-0822)
- 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-2019-0823, CVE-2019-0824, CVE-2019-0825,
CVE-2019-0826, CVE-2019-0827)
- 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-2019-0828)");
