Changes between 1.0.0o and 1.0.0p [xx XXX xxxx]
*) Fix DTLS segmentation fault in dtls1_get_record. A carefully crafted DTLS
message can cause a segmentation fault in OpenSSL due to a NULL pointer
dereference. This could lead to a Denial Of Service attack. Thanks to
Markus Stenberg of Cisco Systems, Inc. for reporting this issue.
(CVE-2014-3571)
[Steve Henson]
*) Fix DTLS memory leak in dtls1_buffer_record. A memory leak can occur in the
dtls1_buffer_record function under certain conditions. In particular this
could occur if an attacker sent repeated DTLS records with the same
sequence number but for the next epoch. The memory leak could be exploited
by an attacker in a Denial of Service attack through memory exhaustion.
Thanks to Chris Mueller for reporting this issue.
(CVE-2015-0206)
[Matt Caswell]
*) Fix issue where no-ssl3 configuration sets method to NULL. When openssl is
built with the no-ssl3 option and a SSL v3 ClientHello is received the ssl
method would be set to NULL which could later result in a NULL pointer
dereference. Thanks to Frank Schmirler for reporting this issue.
(CVE-2014-3569)
[Kurt Roeckx]
*) Abort handshake if server key exchange message is omitted for ephemeral
ECDH ciphersuites.

(CVE-2015-0204)
[Steve Henson]
*) Fixed issue where DH client certificates are accepted without verification.
An OpenSSL server will accept a DH certificate for client authentication
without the certificate verify message. This effectively allows a client to
authenticate without the use of a private key. This only affects servers
which trust a client certificate authority which issues certificates
containing DH keys: these are extremely rare and hardly ever encountered.
Thanks for Karthikeyan Bhargavan of the PROSECCO team at INRIA or reporting
this issue.
(CVE-2015-0205)
[Steve Henson]
*) Correct Bignum squaring. Bignum squaring (BN_sqr) may produce incorrect
results on some platforms, including x86_64. This bug occurs at random
with a very low probability, and is not known to be exploitable in any
way, though its exact impact is difficult to determine. Thanks to Pieter
Wuille (Blockstream) who reported this issue and also suggested an initial
fix. Further analysis was conducted by the OpenSSL development team and
Adam Langley of Google. The final fix was developed by Andy Polyakov of
the OpenSSL core team.
(CVE-2014-3570)
[Andy Polyakov]
*) Fix various certificate fingerprint issues.
By using non-DER or invalid encodings outside the signed portion of a
