Security Bulletin


Summary

There are multiple vulnerabilities in IBM Runtime Environment Java Technology Edition, Version 1.7.0 that is used by Sterling Secure Proxy and Sterling External Authentication Server. These issues were disclosed as part of the IBM Java SDK updates in April 2015.

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 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-2015-1916
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-2015-2808
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-2015-0478
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 https://exchange.xforce.ibmcloud.com/vulnerabilities/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-2015-0204
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)
