"Multiple vulnerabilities has been discovered and corrected in 
openssl :

The dtls1_reassemble_fragment function in d1_both.c in OpenSSL before
0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not
properly validate fragment lengths in DTLS ClientHello messages, which
allows remote attackers to execute arbitrary code or cause a denial of
service (buffer overflow and application crash) via a long non-initial
fragment (CVE-2014-0195).

The dtls1_get_message_fragment function in d1_both.c in OpenSSL before
0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote
attackers to cause a denial of service (recursion and client crash)
via a DTLS hello message in an invalid DTLS handshake (CVE-2014-0221).

OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h
does not properly restrict processing of ChangeCipherSpec messages,
which allows man-in-the-middle attackers to trigger use of a
zero-length master key in certain OpenSSL-to-OpenSSL communications,
and consequently hijack sessions or obtain sensitive information, via
a crafted TLS handshake, aka the CCS Injection vulnerability
(CVE-2014-0224).

The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL
before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when an
anonymous ECDH cipher suite is used, allows remote attackers to cause
a denial of service (NULL pointer dereference and client crash) by
triggering a NULL certificate value (CVE-2014-3470).

The updated packages have been upgraded to the 1.0.0m version where
these security flaws has been fixed."
