A security feature bypass vulnerability exists in Microsoft Outlook software when it improperly handles the parsing of URI formats, aka 'Microsoft Outlook Security Feature Bypass Vulnerability'.CVE-2019-1204microsoftmicrosoft office 2019+6EPSS score4.42%
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).
To exploit the vulnerability, the attacker could send a specially crafted email to a victim. Outlook would then attempt to open a pre-configured message store contained in the email upon receipt of the email.
This update addresses the vulnerability by ensuring Office fully validates incoming email formatting before processing message content.CVE-2019-1199microsoftmicrosoft office 2019+2EPSS score4.65%
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.
