      "title": "Out of bounds read for cookie path",
      "summary": "1. A cookie is set using the `secure` keyword for `https://target`\n2. curl is redirected to or otherwise made to speak with `http://target` (same\n   hostname, but using clear text HTTP) using the same cookie set\n3. The same cookie name is set - but with only a slash as path (`path=\"/\"`).\n   Since this site is not secure, the cookie *should* be ignored.\n4. A bug in the path comparison logic makes curl read outside a heap buffer\n   boundary\n\nThe bug either causes a crash or it potentially makes the comparison come to\nthe wrong conclusion and lets the clear-text site override the contents of the\nsecure cookie, contrary to expectations and depending on the memory contents\nimmediately following the single-byte allocation that holds the path.\n\nThe presumed and correct behavior would be to plainly ignore the second set of\nthe cookie since it was already set as secure on a secure host so overriding\nit on an insecure host should not be okay.",
