A vulnerability has been found and corrected in openssl:
Double free vulnerability in the ssl3_get_key_exchange function in
the OpenSSL client (ssl/s3_clnt.c) in OpenSSL 1.0.0a, 0.9.8, 0.9.7,
and possibly other versions, when using ECDH, allows context-dependent
attackers to cause a denial of service (crash) and possibly execute
