Vulnerability Details

CVE IDs:  CVE-2015-0488 CVE-2015-0478 CVE-2015-0204 CVE-2015-2808 CVE-2015-1916 CVE-2015-0138

DESCRIPTION: This bulletin covers all applicable Java SE CVEs published by Oracle as part of their April 2015 Critical Patch Update and additional vulnerabilties which affect IBM SDK, Java Technology Edition. There are other advisories included in the IBM Java SDK but WebSphere Application Server is not vulnerable to them. You will need to evaluate your own code to determine if you are vulnerable. Please refer to the Reference section for more information on the advisories not applicable to WebSphere Application Server.

CVE-2015-0204 was fixed in IBM SDK, Java Technology Edition under CVE-2015-0138. Both CVEs are included in this advisory for completeness.

CVEID: CVE-2015-0488
DESCRIPTION: An unspecified vulnerability related to the JSSE component could allow a remote attacker to cause a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/102336 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0478
DESCRIPTION: An unspecified vulnerability related to the JCE component could allow a remote attacker to obtain sensitive information.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/102339 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2015-0204
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. This vulnerability is also known as the FREAK attack.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://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-2015-2808
DESCRIPTION: The RC4 algorithm, as used in the TLS protocol and SSL protocol, could allow a remote attacker to obtain sensitive information. An attacker could exploit this vulnerability to remotely expose account credentials without requiring an active man-in-the-middle session. Successful exploitation could allow an attacker to retrieve credit card data or other sensitive information. This vulnerability is commonly referred to as "Bar Mitzvah Attack".
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101851 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)

CVEID: CVE-2015-1916
DESCRIPTION: Server applications which use the IBM Java Secure Socket Extension provider to accept SSL/TLS connections are vulnerable to a denial of service attack due to an unspecified vulnerability.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101995 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0138
DESCRIPTION: A vulnerability in various IBM SSL/TLS implementations could allow a remote attacker to downgrade the security of certain SSL/TLS connections. An IBM SSL/TLS client implementation could accept 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. This vulnerability is also known as the FREAK attack.
