Descriptions
A remote code execution vulnerability exists in Microsoft Word software when it fails to properly handle objects in memory, aka 'Microsoft Word Remote Code Execution Vulnerability'. This CVE ID is unique from CVE-2019-1034.
Existe una vulnerabilidad de ejecución remota de código en el software Microsoft Word, cuando no puede manejar correctamente los objetos en la memoria, también se conoce como "Microsoft Word Remote Code Execution Vulnerability". Este ID de CVE es diferente de CVE-2019-1034.
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.
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.
The security update addresses the vulnerability by correcting how Microsoft Word handles files in memory.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Word. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of tables in Microsoft Word documents. Crafted data in a document can trigger a memory access past the end of an array. An attacker can leverage this vulnerability to execute code in the context of the current process.
