Disclaimer

According to the Forum of Incident Response and Security Teams (FIRST), the
Common Vulnerability Scoring System (CVSS) is an "industry open standard
designed to convey vulnerability severity and help to determine urgency and
priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY
OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF
ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to
address potential vulnerabilities, IBM periodically updates the record of
components contained in our product offerings. As part of that effort, if IBM
identifies previously unidentified packages in a product/service inventory, we
address relevant vulnerabilities regardless of CVE date. Inclusion of an older
CVEID does not demonstrate that the referenced product has been used by IBM
since that date, nor that IBM was aware of a vulnerability as of that date. We
are making clients aware of relevant vulnerabilities as we become aware of
them. "Affected Products and Versions" referenced in IBM Security Bulletins are
intended to be only products and versions that are supported by IBM and have
not passed their end-of-support or warranty date. Thus, failure to reference
unsupported or extended-support products and versions in this Security Bulletin
does not constitute a determination by IBM that they are unaffected by the
vulnerability. Reference to one or more unsupported versions in this Security
Bulletin shall not create an obligation for IBM to provide fixes for any
unsupported or extended-support products or versions.
