Changes between 1.0.2 and 1.1.0 [xx XXX xxxx]
+ *) A missing bounds check in the handling of the TLS heartbeat extension
+ can be used to reveal up to 64k of memory to a connected client or
+ server.
+
+ Thanks for Neel Mehta of Google Security for discovering this bug and to
+ Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for
+ preparing the fix (CVE-2014-0160)

*) Fix for the attack described in the paper "Recovering OpenSSL
ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack"
by Yuval Yarom and Naomi Benger. Details can be obtained from:
to be resent. (CVE-2013-6450)

- *) TLS pad extension: draft-agl-tls-padding-02
+ *) TLS pad extension: draft-agl-tls-padding-03
Workaround for the "TLS hang bug" (see FAQ and PR#2771): if the
TLS client Hello record length value would otherwise be > 255 and
less that 512 pad with a dummy extension containing zeroes so it
is at least 512 bytes long.
- To enable it use an unused extension number (for example chrome uses
- 35655) using:
-
- e.g. -DTLSEXT_TYPE_padding=35655
-
- Since the extension is ignored the actual number doesn't matter as long
- as it doesn't clash with any existing extension.
-
- This will be updated when the extension gets an official number.

*) Call OCSP Stapling callback after ciphersuite has been chosen, so
the right response is stapled. Also change SSL_get_certificate()
so it returns the certificate actually sent.
