Summary

OpenSSL vulnerabilities were disclosed on January 8, 2015 by the OpenSSL 
Project. This includes FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL 
client and server vulnerability. OpenSSL v1.0.0 is used by the DataDirect V7.x
ODBC drivers shipped with WebSphere Message Broker and IBM Integration Bus. 
The drivers have been updated to include OpenSSL v1.0.0r to address the 
applicable CVEs.

Vulnerability Details

CVEID: 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 or the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)

CVEID: 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 the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)

CVEID: CVE-2015-0204 (This vulnerability is also known as the FREAK attack)

DESCRIPTION: A vulnerability in the OpenSSL ssl3_get_key_exchange function 
could allow a remote attacker to downgrade the security of certain TLS 
connections. An OpenSSL client accepts the use of an RSA temporary key in a 
non-export RSA key exchange ciphersuite. This could allow a remote attacker 
using man-in-the-middle techniques to facilitate brute-force decryption of 
TLS/SSL traffic between vulnerable clients and servers.

CVSS Base Score: 4.3

CVSS Temporal Score: See 
http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99707 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVEID: CVE-2015-0209

DESCRIPTION: OpenSSL could allow a remote attacker to execute arbitrary code 
on the system, caused by a use-after-free error in the d2i_ECPrivateKey or 
EVP_PKCS82PKEY function. An attacker could exploit this vulnerability to 
corrupt memory and execute arbitrary code on the system and cause a denial of
service.

CVSS Base Score: 7.5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101674 for the current
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

CVEID: CVE-2015-0286

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error
in the ASN1_TYPE_cmp function when attempting to compare ASN.1 boolean types.
An attacker could exploit this vulnerability to crash any certificate 
verification operation and cause a denial of service.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101666 for the current
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0287

DESCRIPTION: OpenSSL could allow a remote attacker to execute arbitrary code 
on the system, caused by an error related to the reuse of a structure in ASN.1
parsing. An attacker could exploit this vulnerability using an invalid write 
to corrupt memory and execute arbitrary code on the system.

CVSS Base Score: 7.5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101668 for the current
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

CVEID: CVE-2015-0288

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error
in the X509_to_X509_REQ function. An attacker could exploit this vulnerability
to trigger a NULL pointer dereference.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101675 for the current
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0289

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the 
failure to properly handle missing outer ContentInfo by the PKCS#7 parsing 
code. An attacker could exploit this vulnerability using a malformed 
ASN.1-encoded PKCS#7 blob to trigger a NULL pointer dereference.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101669 for the current
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0292

DESCRIPTION: OpenSSL could allow a remote attacker to execute arbitrary code 
on the system, caused by an error when processing base64 encoded data. An 
attacker could exploit this vulnerability using specially-crafted base 64 data
to corrupt memory and execute arbitrary code on the system and cause a denial
of service.

CVSS Base Score: 7.5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101670 for the current
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

CVEID: CVE-2015-0293

DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending a 
specially-crafted SSLv2 CLIENT-MASTER-KEY message, a remote attacker could 
exploit this vulnerability to trigger an assertion.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101671 for the current
score

CVSS Environmental Score*: Undefined
