stunnel before 5.00, when using fork threading, does not properly update
the state of the OpenSSL pseudo-random number generator (PRNG), which
causes subsequent children with the same process ID to use the same entropy
pool and allows remote attackers to obtain private keys for EC (ECDSA) or
DSA certificates.
