 Security
    * Verify results of RSA private key operations to defend
      against Bellcore glitch attack.
+   * Fix a buffer overread in ssl_parse_server_key_exchange() that could cause
+     a crash on invalid input.
+   * Fix a buffer overread in ssl_parse_server_psk_hint() that could cause a
+     crash on invalid input.
 
 Features
    * Extend PKCS#8 interface by introducing support for the entire SHA
      algorithms family when encrypting private keys using PKCS#5 v2.0.
-     Submitted by Antonio Quartulli, OpenVPN Inc.
+     This allows reading encrypted PEM files produced by software that

      by Guido Vranken. #639
    * Fix X509 CRT parsing that would potentially accept an invalid tag when
      parsing the subject alternative names.
+   * Fix a possible arithmetic overflow in ssl_parse_server_key_exchange()
+     that could cause a key exchange to fail on valid data.
+   * Fix a possible arithmetic overflow in ssl_parse_server_psk_hint() that
