Original advisory details:

 Juri 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
 machine-in-the-middle attack and possibly decrypt and modify traffic.
 (CVE-2014-0224)

 Felix Grobert and Ivan Fratric discovered that OpenSSL incorrectly handled
 anonymous ECDH ciphersuites. A remote attacker could use this issue to
 cause OpenSSL to crash, resulting in a denial of service. This issue only
 affected Ubuntu 12.04 LTS, Ubuntu 13.10, and Ubuntu 14.04 LTS.
