The client nonce is intended to protect +against a malicious server. See section 5.10 and 5.12 of RFC 7616 [1], +and bullet point 2 below. + +Tim pointed out that even though it's the MD5 of the nonce that gets sent, +enumerating 31 bits is trivial. So we have still a stack information leak +of 31 bits. + +Furthermore, Tim found the following issues: +* The small size of cnonce might cause the server to erroneously reject + a request due to a repeated (cnonce, nc) pair. As per the birthday + problem 31 bits of randomness will return a duplication with 50% + chance after less than 55000 requests and nc always starts counting at 1. +* The cnonce is intended to protect the client and password against a + malicious server that returns a constant server nonce where the server + precomputed a rainbow table between passwords and correct client response. + As storage is fairly cheap, a server could precompute the client responses + for (a subset of) client nonces and still have a chance of reversing the + client response with the same probability as the cnonce duplication. + + Precomputing the rainbow table for all 2^31 cnonces increases the rainbow + table size by factor 2 billion, which is infeasible. But precomputing it + for 2^14 cnonces only increases the table size by factor 16k and the server + would still have a 10% chance of successfully reversing a password with a + single client request. + +This patch fixes the issues by increasing the nonce size, and checking +the return value of php_random_bytes_throw().
