Security Bulletin
Summary
There are multiple vulnerabilities in IBM SDK Java Technology Edition, Version
6 and 7, that is used by IBM PureApplication System. 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-2015-2808
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.
