There’s a libcurl.dll in my system32

Daniel Stenberg explains why curl's maintainers cannot patch a vulnerable libcurl.dll found lurking in Windows System32 folders. Third-party applications bundle their own libcurl.dll files during installation, sometimes dropping them in system32, and only the app that built and shipped that specific file can safely rebuild and update it. Microsoft's own bundled curl in Windows is statically linked and never produces a libcurl.dll, so any such file comes from another installed application. The curl team's advice: use tools like tasklist to identify which running application depends on the DLL, then get that vendor to rebuild with a patched curl. The team offers build guidance, long-term stable releases, and security backports, but cannot runtime-patch someone else's Windows installation.
