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 https://exchange.xforce.ibmcloud.com/vulnerabilities/93586 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-2014-0198

**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 https://exchange.xforce.ibmcloud.com/vulnerabilities/93000 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 multithreaded environment to inject data into an SSL stream and cause a denial of service.

CVSS Base Score: 4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/92632 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
