CVE-2014-2900 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-2900): wolfSSL CyaSSL before 2.9.4 does not properly validate X.509 certificates with unknown critical extensions, which allows man-in-the-middle attackers to spoof servers via crafted X.509 certificate. CVE-2014-2899 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-2899): wolfSSL CyaSSL before 2.9.4 allows remote attackers to cause a denial of service (NULL pointer dereference) via (1) a request for the peer certificate when a certificate parsing failure occurs or (2) a client_key_exchange message when the ephemeral key is not found.
