Security Bulletin
Summary
There are multiple vulnerabilities in IBM SDK Java Technology Edition version that is used by the IBM FlashSystem 840. These issues were disclosed as part of the IBM SDK, Java Technology Edition Quarterly CPU - April 2015. A man-in-the-middle exploit of one of these vulnerabilities could result in brute-force decryption of TLS/SSL traffic between vulnerable clients and servers. Exploit of the other vulnerabilities could result in a denial of service.
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-2015-1916
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
