CVE-2024-11053 — netrc and redirect credential leak

Affected: curl, Siemens COMOS V10.4.5, Siemens COMOS V10.6, Siemens RUGGEDCOM RST2428P, Siemens SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 family, Siemens SCALANCE XCH328, Siemens SCALANCE XCM324, Siemens SCALANCE XCM328, Siemens SCALANCE XCM332, Siemens SCALANCE XRH334 (24 V DC, 8xFO, CC) and 12 more

When asked to both use a `.netrc` file for credentials and to follow HTTP redirects, curl could leak the password used for the first host to the followed-to host under certain circumstances.

This flaw only manifests itself if the netrc file has an entry that matches the redirect target hostname but the entry either omits just the password or omits both login and password.
