openssl: only allow ephemeral RSA keys in export ciphersuites (FREAK)
It was discovered that OpenSSL would accept ephemeral RSA keys when using non-export RSA cipher suites. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method...
OpenSSL DHE Client Key Exchange Denial of Service (CVE-2015-1787)
A denial of service vulnerability exists in OpenSSL. The vulnerability is due to a null pointer dereference that occurs when an OpenSSL application receives and processes a Client Certificate and a crafted Client Key Exchange handshake message.A remote, unauthenticated attacker can exploit this...

libssh2: out-of-bounds read
When negotiating a new SSH session with a remote server, one of libssh2's functions for doing the key exchange kexagreemethods was naively reading data from the incoming packet and using it without doing sufficient range checks. The SSHMSGKEXINIT packet arrives to libssh2 with a set of strings,...
Cisco IOS IKEv2 DoS (cisco-sa-20150325-ikev2)
According to its self-reported version, the Cisco IOS software running on the remote device is affected by a denial of service vulnerability in the Internet Key Exchange version 2 IKEv2 subsystem due to improper handling of specially crafted IKEv2 packets. A remote, unauthenticated attacker can...
