      PeopleSoft LONGCHAR and VARCHAR Data Upload (DoS)
    ------------------------------------------------------------------------

    SUMMARY

    PeopleSoft's LONGCHAR and VARCHAR fields allow potentially large amounts
    of data to be uploaded. These fields default to the maximum allowed size
    for their data type established on the database. This would allow
    attackers to cause a denial of service against the product.

    DETAILS

    Vulnerable systems:
     * PeopleSoft version 8.42

    Vendor Solution:
    The database can be configured to limit the size of these data types;
    however, this should be tested to assess the impact to the application.
    Consider also looking at modifying the field definitions within the
    Application. Restricting size with the field definition would prevent
    using these LONG fields to upload large amounts of data. Note that making
    any changes to the delivered application is considered a customization
    beyond the scope of the Global Support Center. Make sure and take a backup
    of the data before making such changes.

    Vendor Status:
    3 June 03 PeopleSoft contacted
    3 June 03 PeopleSoft confirms
    24 June 03 PeopleSoft teleconference
    19 July 03 PeopleSoft posts to Customer Connection
