Vulnerability Details:

CVE-ID: CVE-2014-0224

Description: OpenSSL is vulnerable to a man-in-the-middle attack, caused by the use of weak keying material in SSL/TLS clients and servers. A remote attacker could exploit this vulnerability using a specially-crafted handshake to conduct man-in-the-middle attacks to decrypt and modify traffic.

CVSS Base Score: 5.8
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/93586&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:N)

CVE-ID: CVE-2014-0221

Description: OpenSSL is vulnerable to a denial of service, caused by a recursion error in the DTLS client. By sending an invalid DTLS handshake, a remote attacker could exploit this vulnerability to cause the application to crash.

CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/93587&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-0195

Description: OpenSSL is vulnerable to a buffer overflow. By sending invalid DTLS packet fragments, a remote attacker could exploit this vulnerability to overrun the client or server and execute arbitrary code on a DTLS client or server.

CVSS Base Score: 7.5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/93588&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

CVE-ID: CVE-2014-0198

Description: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in the do_ssl3_write() function. If SSL_MODE_RELEASE_BUFFERS is enabled, a remote attacker could exploit this vulnerability to cause the application to crash.

CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/93000&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2010-5298

Description: OpenSSL is vulnerable to a denial of service, caused by a race condition in the ssl3_read_bytes function. If SSL_MODE_RELEASE_BUFFERS is enabled, an attacker could exploit this vulnerability using an SSL connection in a multi-threaded environment to inject data into an SSL stream and cause a denial of service.

CVSS Base Score: 4
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/92632&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:P)

CVE-ID: CVE-2014-3470

Description: OpenSSL is vulnerable to a denial of service, caused by the implementation of anonymous ECDH ciphersuites. A remote attacker could exploit this vulnerability to cause a denial of service.

CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/93589&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
