Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

The OpenSSL Project reports :

An attacker using a carefully crafted handshake can force the use of
weak keying material in OpenSSL SSL/TLS clients and servers. This can
be exploited by a Man-in-the-middle (MITM) attack where the attacker
can decrypt and modify traffic from the attacked client and server.
[CVE-2014-0224]

By sending an invalid DTLS handshake to an OpenSSL DTLS client the
code can be made to recurse eventually crashing in a DoS attack.
[CVE-2014-0221]

A buffer overrun attack can be triggered by sending invalid DTLS
fragments to an OpenSSL DTLS client or server. This is potentially
exploitable to run arbitrary code on a vulnerable client or server.
[CVE-2014-0195]

OpenSSL TLS clients enabling anonymous ECDH ciphersuites are subject
to a denial of service attack. [CVE-2014-3470]
