Security Bulletin

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 (CVE-2015-0488, CVE-2015-0478, CVE-2015-2808,
CVE-2015-1916, CVE-2015-0204). 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)
