Security Bulletin

Summary

There are multiple vulnerabilities in IBM Runtime Environment Java Technology
Edition, Versions 6 and 7 that are used by WebSphere DataPower XC10 Appliance.
These issues were disclosed as part of the IBM Java SDK updates in January 
2016 and includes the vulnerability commonly referred to as SLOTH.

Vulnerability Details

CVEID: CVE-2016-0475

DESCRIPTION: An unspecified vulnerability in Oracle Java SE Java SE Embedded 
and Jrockit related to the Libraries component has partial confidentiality 
impact, partial integrity impact, and no availability impact.

CVSS Base Score: 5.8

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/109946 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:N)

CVEID: CVE-2015-7575

DESCRIPTION: The TLS protocol could allow weaker than expected security caused
by a collision attack when using the MD5 hash function for signing a 
ServerKeyExchange message during a TLS handshake. An attacker could exploit 
this vulnerability using man-in-the-middle techniques to impersonate a TLS 
server and obtain credentials. This vulnerability is commonly referred to as 
SLOTH.

CVSS Base Score: 7.1

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/109415 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N)

CVEID: CVE-2016-0448

DESCRIPTION: An unspecified vulnerability in Oracle Java SE and Java SE 
Embedded related to the JMX component could allow a remote attacker to obtain
sensitive information resulting in a partial confidentiality impact using 
unknown attack vectors.

CVSS Base Score: 4

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/109949 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:N)

Affected Products and Versions

WebSphere DataPower XC10 Appliance Version 2.1

WebSphere DataPower XC10 Appliance Version 2.5

Remediation/Fixes

Apply an interim fix, according to the table below. Interim fixes are 
associated with the original APAR that is documented in the table. Because 
these APAR references might be updated to more recent APARs, see the links in
the table for the most recent interim fix information.

This interim fix contains a new default SSL certificate, as the previous 
default SSL certificate, which was never intended for production use, has an 
MD5 signature and is no longer compatible with Java. The result is that 
installing this interim fix will make it incompatible with any WebSphere 
Datapower XC10 appliances that are running with an MD5 certificate, including
the default SSL certificate that was shipped prior to this interim fix. If the
appliance is configured with a custom keystore and certificate with an MD5 
signature, it must be replaced prior to upgrading to this interim fix or the 
'clear-tls-config' command must be run on the appliance before or after 
performing the upgrade. Failing to do so will result in the appliance failing
to start. Note that changing the active certificate for an appliance 
collective does require that the cache be reloaded and client truststores must
be configured to trust the new certificate.

Product 				Version 				APAR 		Link to interim fix

WebSphere DataPower XC10 Appliance 	2.1 					IT13446 	Refer to the Version 2.1 table in Recommended fixes for WebSphere DataPower XC10 Appliance.
 V2.1 on appliance 9235-92X 		

WebSphere DataPower XC10 Appliance 	2.1 					IT13446		Refer to the Version 2.1 table in Recommended fixes for WebSphere DataPower XC10 Appliance.
 V2.1 on appliance 7199-92X 

WebSphere DataPower XC10 Appliance 	Version 2.5 with 			IT13446 	Refer to the Version 2.5 table in Recommended fixes for WebSphere DataPower XC10 Appliance.
 V2.5 on appliance 7199-92X		SSD drivers

					Important: See More Information 
					link and follow instructions to 
					determine if you have an old or 
					newer SSD driver on your appliance 
					using the show ssd-version command. 	
												 

WebSphere DataPower XC10 Appliance 	2.5 					IT13446 	Refer to the Version 2.5 table in Recommended fixes for WebSphere DataPower XC10 Appliance.

Workarounds and Mitigations

There is no workaround. The interim fix must be applied to correct the 
problem.
