From 0.9 ChangeLog:
    * Fixes a critical denial-of-service with x.509 certificate verification:
      peer may cause xyssl to loop indefinitely by sending a cert. for which
      the PKCS#1 RSA signature check fails (bug reported by Benoit)
...
    * Modified ssl_parse_client_key_exchange() to protect against
      Daniel Bleichenbacher attack on PKCS#1 v1.5 padding, as well as
      the Klima-Pokorny-Rosa extension of Bleichenbacher's attack
