NIST CVE Summary

  1. A cookie is set using the `secure` keyword for `https://target\`
  2. curl is redirected to or otherwise made to speak with `http://target\` (same hostname, but using clear text HTTP) using the same cookie set
  3. The same cookie name is set - but with just a slash as path (`path=\"/\",`). Since this site is not secure, the cookie should just be ignored.
  4. A bug in the path comparison logic makes curl read outside a heap buffer boundary

The bug either causes a crash or it potentially makes the comparison come to the wrong conclusion and lets the clear-text site override the contents of the secure cookie, contrary to expectations and depending on the memory contents immediately following the single-byte allocation that holds the path.

The presumed and correct behavior would be to plainly ignore the second set of the cookie since it was already set as secure on a secure host so overriding it on an insecure host should not be okay.
