communications.

CVE-2014-0221 may allow an attacker to crash a DTLS client with an invalid handshake.

CVE-2014-0195 can result in a buffer overrun attack by sending invalid DTLS fragments to an OpenSSL DTLS client or server.

CVE-2014-0198 and CVE-2010-5298 may allow an attacker to cause a denial of service under certain conditions, when SSL_MODE_RELEASE_BUFFERS
is enabled.

CVE-2014-3470 may allow an attacker to trigger a denial of service in SSL clients when anonymous ECDH ciphersuites are enabled. This issue
does not affect Fortinet products.

CVE-2014-0076 can be used to discover ECDSA nonces on multi-user systems by exploiting timing attacks in CPU L3 caches. This does not apply
to Fortinet products.");
