+Subject: [PATCH] Fix missing randomness check and insufficient random bytes
+ for SOAP HTTP Digest
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If php_random_bytes_throw fails, the nonce will be uninitialized, but
+still sent to the server. 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(). In the process we also get
+rid of the MD5 hashing of the nonce.
