Summary
Integer overflows in URL parser
Details

libcurl contains two integer overflows in the curl_url_set() function that if triggered, can lead to a too small buffer allocation and a subsequent heap buffer overflow.

The flaws only exist on 32-bit architectures and require excessive string input lengths.
