Details:

Jüri Aedla discovered that OpenSSL incorrectly handled invalid DTLS
fragments. A remote attacker could use this issue to cause OpenSSL to
crash, resulting in a denial of service, or possibly execute arbitrary
code. This issue only affected Ubuntu 12.04 LTS, Ubuntu 13.10, and
Ubuntu 14.04 LTS. (CVE-2014-0195)

Imre Rad discovered that OpenSSL incorrectly handled DTLS recursions. A
remote attacker could use this issue to cause OpenSSL to crash, resulting
in a denial of service. (CVE-2014-0221)

KIKUCHI Masashi discovered that OpenSSL incorrectly handled certain
handshakes. A remote attacker could use this flaw to perform a
man-in-the-middle attack and possibly decrypt and modify traffic.
(CVE-2014-0224)

Felix Gröbert and Ivan Fratrić discovered that OpenSSL incorrectly handled
anonymous ECDH ciphersuites. A remote attacker could use this issue to
