When a server is sending invalid DH values during a handshake a BIGNUM value is not properly initialized. This causes a null pointer dereference in a s2n based client leading to a crash or possible worse on old systems (e.g. on Debian kernels lower than 2.6.26). Technical details and a patch are available here: https://github.com/awslabs/s2n/pull/124 The fix was merged and is in commit 9af6ba1815dfd5c00361cc3bd45cee1d64e0c3bf.
