UBUNTU-CVE-2015-0205
The ssl3getcertverify function in s3srvr.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k accepts client authentication with a Diffie-Hellman DH certificate without requiring a CertificateVerify message, which allows remote attackers to obtain access without knowledge of a private key via...
OpenSSL Ephemeral ECDH Cipher Suite Handshake Downgrade (CVE-2014-3572)
A vulnerability has been detected in the way OpenSSL handles TLS handshakes involving certain cipher suites. An attacker might leverage this vulnerability to impersonate a server and intercept secure communications...
Vulnerability in OpenSSL - ECDHE silently downgrades to ECDH [Client]
An OpenSSL client will accept a handshake using an ephemeral ECDH ciphersuite using an ECDSA certificate if the server key exchange message is omitted. This effectively removes forward secrecy from the ciphersuite. Found by Karthikeyan Bhargavan of the PROSECCO team at INRIA...
LibreSSL Double Release Vulnerability
LibreSSL is a fork of the OpenSSL cryptographic software library developed by the OpenBSD project and an open source implementation of the Secure Sockets Layer SSL and Transport Layer Security TLS protocols. A double-release vulnerability exists in the 'sslparseclienthellousesrtpext' function in...

CVE-2014-9424
CVE-2014-9424 affects LibreSSL prior to 2.1.2. The vulnerability is a double-free in ssl_parse_clienthello_use_srtp_ext() within d1_srtp.c, which can trigger a length-verification error during DTLS handshake and may cause a denial of service (or unspecified impact). The issue is fixed by upgradin...
OpenSSL 's23_srvr.c' Denial of Service Vulnerability
