Summary

There are multiple vulnerabilities in IBM SDK Java Technology Edition,
Versions 6 and 7 that is used by IBM Rational Application Developer for
WebSphere Software. These issues were disclosed as part of the IBM Java
SDK updates in April 2015.

This bulletin also addresses FREAK: "Factoring Attack on RSA-EXPORT keys"
SSL/TLS vulnerability and RC4 Bar Mitzvah Attack for SSL/TLS vulnerability.

Vulnerability Details

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)
