Descriptions

<p>A remote code execution vulnerability exists when the Windows Text Service Module improperly handles memory. An attacker who successfully exploited the vulnerability could gain execution on a victim system.</p>
<p>An attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge (Chromium-based), and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements by adding specially crafted content that could exploit the vulnerability. In all cases, however, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by way of enticement in an email or Instant Messenger message, or by getting them to open an attachment sent through email.</p>
<p>The security update addresses the vulnerability by correcting how the Windows Text Service Module handles memory.</p>

Se presenta una vulnerabilidad de ejecución de código remota cuando el Windows Text Service Module maneja inapropiadamente la memoria, también se conoce como "Windows Text Service Module Remote Code Execution Vulnerability"

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Microsoft Internet Explorer. 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 CTSF3CandidateMessage objects in the MSCTF module. By manipulating a document's elements, an attacker can cause a pointer to be reused after it has been freed. An attacker can leverage this vulnerability to execute code in the context of the current process at low integrity.
