Sockets Layer toolkit. The Common Vulnerabilities and Exposures
project identifies the following issues :
CVE-2014-3570
Pieter Wuille of Blockstream reported that the bignum squaring
(BN_sqr) may produce incorrect results on some platforms, which might
make it easier for remote attackers to defeat cryptographic protection
mechanisms.
CVE-2014-3571
Markus Stenberg of Cisco Systems, Inc. reported that a carefully
crafted DTLS message can cause a segmentation fault in OpenSSL due to
a NULL pointer dereference. A remote attacker could use this flaw to
mount a denial of service attack.
CVE-2014-3572
Karthikeyan Bhargavan of the PROSECCO team at INRIA reported that an
OpenSSL client would accept a handshake using an ephemeral ECDH
ciphersuite if the server key exchange message is omitted. This allows
remote SSL servers to conduct ECDHE-to-ECDH downgrade attacks and
trigger a loss of forward secrecy.
CVE-2014-8275
Antti Karjalainen and Tuomo Untinen of the Codenomicon CROSS project
and Konrad Kraszewski of Google reported various certificate
fingerprint issues, which allow remote attackers to defeat a
fingerprint-based certificate-blacklist protection mechanism.
CVE-2015-0204
Karthikeyan Bhargavan of the PROSECCO team at INRIA reported that an
OpenSSL client will accept the use of an ephemeral RSA key in a
non-export RSA key exchange ciphersuite, violating the TLS standard.
This allows remote SSL servers to downgrade the security of the
session.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.
