Error description

  • Using 'EXEC CICS WEB READ HTTPHEADER' with a VALUELEN that is

    data moved to the buffer will not be truncated, resuting in an
    overlay.

    * PROBLEM DESCRIPTION: Storage overlay using EXEC CICS WEB     *
    *                      READ HTTPHEADER with the VALUE option.  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When using the command EXEC CICS WEB READ HTTPHEADER, a storage
    overlay can occur if the length of the httpheader is larger than
    the VALUELENGTH supplied by the application. The cause is that
    the wrong length is used when copying data to the application's
    buffer. Instead of using the VALUELENGTH specified by the
    application, the length of the actual data is used. The command
    correctly returns a LENGERR response.

Problem conclusion

  • DFHWBAP has been changed to ensure that data is not written
    beyond the end of the buffer provided by the application.
