Changes between 1.0.1g and 1.0.1h [5 Jun 2014]
*) Fix for SSL/TLS MITM flaw. An attacker using a carefully crafted
handshake can force the use of weak keying material in OpenSSL
SSL/TLS clients and servers.
Thanks to KIKUCHI Masashi (Lepidum Co. Ltd.) for discovering and
researching this issue. (CVE-2014-0224)
[KIKUCHI Masashi, Steve Henson]
*) Fix DTLS recursion flaw. By sending an invalid DTLS handshake to an
OpenSSL DTLS client the code can be made to recurse eventually crashing
in a DoS attack.
Thanks to Imre Rad (Search-Lab Ltd.) for discovering this issue.
(CVE-2014-0221)
[Imre Rad, Steve Henson]
*) Fix DTLS invalid fragment vulnerability. A buffer overrun attack can
be triggered by sending invalid DTLS fragments to an OpenSSL DTLS
client or server. This is potentially exploitable to run arbitrary
code on a vulnerable client or server.
Thanks to Jüri Aedla for reporting this issue. (CVE-2014-0195)
[Jüri Aedla, Steve Henson]
*) Fix bug in TLS code where clients enable anonymous ECDH ciphersuites
are subject to a denial of service attack.
Thanks to Felix Gröbert and Ivan Fratric at Google for discovering
this issue. (CVE-2014-3470)
[Felix Gröbert, Ivan Fratric, Steve Henson]
*) Harmonize version and its documentation. -f flag is used to display
compilation flags.

*) Fix eckey_priv_encode so it immediately returns an error upon a failure
in i2d_ECPrivateKey.
[mancha <mancha1@zoho.com>]
*) Fix some double frees. These are not thought to be exploitable.

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:

was actually wanted.
The effect of this bug is that only a few bytes of the hostname are mixed
into the random seed, instead of using the entire hostname.
