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:
