A remote code execution vulnerability exists in Microsoft Outlook 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. 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. Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Outlook 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 designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file. Note that where severity is indicated as Critical in the Affected Products table, the Preview Pane is an attack vector. The security update addresses the vulnerability by correcting how Outlook handles objects in memory.

The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in     Microsoft Outlook 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-2019-1200)

  - A remote code execution vulnerability exists in     Microsoft Outlook 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-2019-1199)

  - An elevation of privilege vulnerability exists when     Microsoft Outlook initiates processing of incoming     messages without sufficient validation of the formatting     of the messages. An attacker who successfully exploited     the vulnerability could attempt to force Outlook to load     a local or remote message store (over SMB).
    (CVE-2019-1204)

  - 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-2019-1201,     CVE-2019-1205)

  - A remote code execution vulnerability exists when the     Windows Jet Database 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 Windows Jet Database Engine handles objects in     memory. (CVE-2019-1155)
