Security Bulletin
Summary
There are multiple vulnerabilities in IBM SDK Java Technology Edition that
is shipped with IBM WebSphere Service Registry and Repository. These issues
were disclosed as part of the IBM Java SDK updates in April 2015.
Vulnerability Details
CVE-2015-0204 was fixed in IBM SDK, Java Technology Edition under
CVE-2015-0138. Both CVEs are included in this advisory for completeness.
CVEID: CVE-2015-0488
DESCRIPTION: An unspecified vulnerability 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 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-2015-0204
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-2015-2808
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-2015-1916
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-2015-0138
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.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/100691 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
