El gancho
ATL vulnerabilities are easy to overstate from source metadata alone. MS09-035 affects components and controls built with vulnerable-era Microsoft ATL headers, including CVE-2009-0901 and CVE-2009-2493 remote-code-execution context plus CVE-2009-2495 information-disclosure context, so the useful repo signal is whether a project still appears to build ATL code with legacy Visual C++ metadata that needs patch-inventory and rebuild review.
Cómo funciona
The repo check correlates Visual C++ project metadata with ATL header usage in the same project area. The finding stays scoped to source/build evidence and does not claim FixVibe inspected the build machine, proved an unpatched ATL installation, confirmed an ActiveX control is deployed, or triggered malformed stream handling.
El radio de impacto
If an ATL-built component or control was compiled with affected headers and is reachable under the advisory conditions, a malicious document or web page may be able to reach code-execution or information-disclosure behavior in the user's context. A repo match should drive toolchain patching and binary rebuild verification before treating it as confirmed production exposure.

Defensas a prueba de balas
Apply the Microsoft MS09-035 ATL update to every build environment or migrate to a supported patched Visual C++ toolset, then rebuild and redistribute every ATL-built COM object, ActiveX control, DLL, installer, or application artifact. Verify deployed binary provenance and patch inventory before closing the advisory.
