Outlook 2016 / 2019 / 365 Update for August 2020

News

A new rollup update has been made available for all Click-to-Run installations of Outlook 2016, Outlook 2019 and Outlook as part of a Microsoft 365 subscription.

It contains 13 security updates for Access (1), Excel (5), Outlook (2), Word (3) and Office (2). The Details about the Outlook vulnerability;

  • CVE-2020-1483: Microsoft Outlook Memory Corruption Vulnerability
    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. 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.
    To exploit the vulnerability, a user must 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.
    Note that the Preview Pane is an attack vector for this vulnerability.
    The security update addresses the vulnerability by correcting how Microsoft Outlook handles files in memory.
  • CVE-2020-1493: Microsoft Outlook Information Disclosure Vulnerability
    An information disclosure vulnerability exists when attaching files to Outlook messages. This vulnerability could potentially allow users to share attached files such that they are accessible by anonymous users where they should be restricted to specific users.
    To exploit this vulnerability, an attacker would have to attach a file as a link to an email. The email could then be shared with individuals that should not have access to the files, ignoring the default organizational setting.
    The security update addresses the vulnerability by correcting how Outlook handles file attachment links.

In addition, it contains 2 documented non-security fixes for Outlook Current, 4 features and 7 fixes for Monthly Enterprise 2005, 1 for Semi-Annual 2002. Most notable fixes are;

    File-> Options-> Mail-> section: Send Messages-> Suggest names to mention when I use the @ symbol in a message.
  • Version 2006 – Keep your pictures high fidelity when sending them as part of an email
