Security Bulletin

Summary

There are multiple vulnerabilities in IBM Runtime Environment Java Technology
Edition, Versions 6 and 7 that are used by WebSphere eXtreme Scale. 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 eXtreme Scale 7.1.0

WebSphere eXtreme Scale 7.1.1

WebSphere eXtreme Scale 8.5

WebSphere eXtreme Scale 8.6

Remediation/Fixes

Since MD5 signatures are no longer compatible with Java, installing this 
interim fix will make it incompatible with any WebSphere eXtreme Scale clients
and servers that are running with an MD5 certificate. If any WebSphere eXtreme
Scale clients or servers are configured with a certificate with an MD5 
signature, they must be replaced prior to starting after upgrading to this 
interim fix. Failing to do so will result in the clients and servers failing 
to connect to each other. Note that client truststores must be configured to 
trust the new certificate.

<Product 			VRMF 	APAR 		Remediation/First Fix

WebSphere eXtreme Scale 	7.1 	PI56344 	Refer to the Version 7.1 table in the Recommended Fixes page for WebSphere eXtreme Scale.

WebSphere eXtreme Scale 	7.1.1	PI56341 	Refer to the Version 7.1.1, 8.5, or 8.6 table in the Recommended Fixes page for WebSphere eXtreme Scale.
				8.5
				8.6	

Workarounds and Mitigations

No workaround exists. If you are running WebSphere eXtreme Scale standalone, 
apply the appropriate fix from the previous table. If you are running 
WebSphere eXtreme Scale clients or servers that are embedded in WebSphere 
Application Server, apply the appropriate fix for WebSphere Application 
Server, which is described here: 
https://www-304.ibm.com/support/docview.wss?uid=swg21962931
