Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server                                      *
    *                  who is running WebSphere Business Process   *

    ****************************************************************
    * PROBLEM DESCRIPTION: When X-Content-Type-Options header is   *
    *                      configured in BPM, WebSphere's logout   *
    *                      panel appears as source code in the     *
    *                      browser.                                *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When X-Content-Type-Option header is set, browsers are not
    supposed to guess content type.  ibm_security_logout page did
    not
    have content type explicitly set to "text/html", so the browsers
    showed source code.
    

Problem conclusion

  • With this apar, the content type for logout page is set to
    "text/html" so that browser will display the page correctly.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.14 and 9.0.0.8.  Please refer to the Recommended
