Security Updates for Outlook (February 2018)

High Nessus Plugin ID 106807

Synopsis

The Microsoft Outlook application installed on the remote host is affected by multiple vulnerabilities.

Description

The Microsoft Outlook application installed on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

- 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-2018-0850)

- 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-2018-0852)

Microsoft has released the following security updates to address this issue:
- KB4011682
