Security Bulletin: Vulnerabilities in OpenSSL affect IBM Flex System Manager (FSM) SMIA Configuration Tool. (CVE-2014-3569, CVE-2014-3570, CVE-2014-3571, CVE-2014-3572, CVE-2014-8275, CVE-2014-0205, CVE-2014-0206)

Vulnerability Details

Summary

OpenSSL vulnerabilities were disclosed on January 8, 2015 by the OpenSSL Project. OpenSSL is used by IBM Flex System Manager (FSM) SMIA Configuration Tool, SMIA Configuration Tool has addressed the applicable CVEs.

Vulnerability Details

CVE-ID: CVE-2014-3569

Description: OpenSSL is vulnerable to a denial of service, caused by the failure to properly handle attempts to use unsupported protocols by the ssl23_get_client_hello function in s23_srvr.c. A remote attacker could exploit this vulnerability using an unexpected handshake to trigger a NULL pointer dereference and cause the daemon to crash.

CVSS Base Score: 5
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/99706 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3570

Description: An unspecified error in OpenSSL related to the production of incorrect results on some platforms by Bignum squaring (BN_sqr) has an unknown attack vector and impact.

CVSS Base Score: 2.6
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/99710 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2014-3571

Description: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference when handling malicious messages. By sending a specially-crafted DTLS message, a remote attacker could exploit this vulnerability to cause a segmentation fault.

CVSS Base Score: 5
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/99703 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3572

Description: OpenSSL could provide weaker than expected security. The client accepts a handshake using an ephemeral ECDH ciphersuite with the server key exchange message omitted. An attacker could exploit this vulnerability to launch further attacks on the system.

CVSS Base Score: 1.2
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/99705 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2014-8275

Description: OpenSSL could allow a local attacker to bypass security restrictions, caused by the modification of the fingerprint without breaking the signature. An attacker could exploit this vulnerability using non-DER or invalid encodings outside the signed portion of a certificate bypass security restrictions and perform unauthorized actions.

CVSS Base Score: 1.2
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/99709 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2015-0205

Description: OpenSSL could allow a remote authenticated attacker to bypass security restrictions, caused by the acceptance of a DH certificate for client authentication without verification. An attacker could exploit this vulnerability to authenticate without the use of a private key.

CVSS Base Score: 2.1
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/99708 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:S/C:N/I:P/A:N)

CVE-ID: CVE-2015-0206

Description: OpenSSL is vulnerable to a denial of service, caused by a memory leak in the dtls1_buffer_record function. By sending repeated DTLS records with the same sequence number, a remote attacker could exploit this vulnerability to exhaust all available memory resources.

CVSS Base Score: 5
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/99704 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
