| Description: |
From the Mageia advisory:
A flaw was found in the way stunnel, a socket wrapper which can provide
SSL support to ordinary applications, performed (re)initialization of PRNG
after fork. When accepting a new connection, the server forks and the
child process handles the request. The RAND_bytes() function of openssl
doesn't reset its state after the fork, but seeds the PRNG with the output
of time(NULL). The most important consequence is that servers using EC
(ECDSA) or DSA certificates may under certain conditions leak their
private key. |
