CVE-ID: CVE-2014-5139

Description: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference when an SRP ciphersuite is specified without being properly negotiated with the client. A remote attacker could exploit this vulnerability to cause the client to crash.

**CVSS Base Score:**5
**CVSS Temporal Score:**See <https://exchange.xforce.ibmcloud.com/vulnerabilities/95166&gt; for more information
*CVSS Environmental Score:**Undefined
CVSS Vector:(AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3511

Description: OpenSSL could allow a remote attacker to bypass security restrictions, caused by the negotiation of TLS 1.0 instead of higher protocol versions by the OpenSSL SSL/TLS server code when handling a badly fragmented ClientHello message. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to TLS 1.0.

CVSS Base Score: 4.3 **CVSS Temporal Score:**See <https://exchange.xforce.ibmcloud.com/vulnerabilities/95162&gt; for more information *CVSS Environmental Score:**Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2014-3509

Description: OpenSSL is vulnerable to a denial of service, caused by a race condition in the ssl_parse_serverhello_tlsext() code. If a multithreaded client connects to a malicious server using a resumed session, a remote attacker could exploit this vulnerability to cause a denial of service.

CVSS Base Score: 4.3 **CVSS Temporal Score:**See <https://exchange.xforce.ibmcloud.com/vulnerabilities/95159&gt; for more information *CVSS Environmental Score:**Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
