Security Bulletin: Multiple vulnerabilities in IBM SDK Java Technology Edition
affect IBM Business Process Manager and WebSphere Lombardi Edition April 2015
CPU

Security Bulletin

Summary

There are multiple vulnerabilities in IBM SDK Java Technology Edition that is
shipped with IBM WebSphere Application Server. These issues were disclosed as
part of the IBM Java SDK updates in April 2015.

Vulnerability Details

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 in Oracle Java SE and Jrockit 
related to the JSSE component could allow a remote attacker to cause a denial
of service.

CVSS Base Score: 5

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/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 in Oracle Java SE and JRockit 
related to the JCE component could allow a remote attacker to obtain sensitive
information.

CVSS Base Score: 4.3

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/102339 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/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 http://xforce.iss.net/xforce/xfdb/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 http://xforce.iss.net/xforce/xfdb/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-2015-0204

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 http://xforce.iss.net/xforce/xfdb/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-2015-0138

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.

CVSS Base Score: 4.3

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/100691 for the 
current score

CVSS Environmental Score*: Undefined

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