Microsoft Word Remote Code Execution Vulnerability

Microsoft is investigating reports of a series of remote code execution vulnerabilities impacting Windows and Office products. Microsoft is aware of targeted attacks that attempt to exploit these vulnerabilities by using specially-crafted Microsoft Office documents.

An attacker could create a specially crafted Microsoft Office document that enables them to perform remote code execution in the context of the victim. However, an attacker would have to convince the victim to open the malicious file.

Upon completion of this investigation, Microsoft will take the appropriate action to help protect our customers. This might include providing a security update through our monthly release process or providing an out-of-cycle security update, depending on customer needs.

Please see the Microsoft Threat Intelligence Blog https://aka.ms/Storm-0978  Entry for important information about steps you can take to protect your system from this vulnerability.

This CVE will be updated with new information and links to security updates when they become available.

An information disclosure vulnerability exists when Microsoft Word improperly discloses the contents of its memory, aka 'Microsoft Word Information Disclosure Vulnerability'. This CVE ID is unique from CVE-2020-1502, CVE-2020-1503.

An information disclosure vulnerability exists when Microsoft Word improperly discloses the contents of its memory, aka 'Microsoft Word Information Disclosure Vulnerability'. This CVE ID is unique from CVE-2020-1502, CVE-2020-1583.

<p>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.</p> <p>To exploit the vulnerability, a user must open a specially crafted file with an affected version of Microsoft Word 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 that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file.</p> <p>The security update addresses the vulnerability by correcting how Microsoft Word handles files in memory.</p>
