ERROR DESCRIPTION:
WebSphere Application Server could allow an HTTP response splitting attack.

LOCAL FIX:

PROBLEM SUMMARY:
WebSphere Application Server is vulnerable to HTTP response splitting attacks.
A remote attacker could exploit this vulnerability using specially-crafted URL to cause the server to return a split response, once the URL is clicked.
This would allow the attacker to perform further attacks, such as Web cache poisoning, cross-site scripting, and possibly obtain sensitive information.

PROBLEM CONCLUSION:
An update was made to prevent the vulnerability.
The fix for this APAR is currently targeted for inclusion in fix packs
7.0.0.39, 8.0.0.12 and 8.5.5.8.
