    Hello,
    Please note that Oracle has updated the extproc buffer overrun advisory.
    There was some confusion caused because the intial Oracle advisory stated
    that a username and password were required to exploit the overflow which was
    contrary to the results of our research; we concluded that no user ID or
    password was necessary. Whilst I answered many of the mails querying this
    discrepancy, for those that I did not have a chance to reply to, please
    accept my apologies. The updated Oracle can be found here :
    http://otn.oracle.com/deploy/security/pdf/2003alert57.pdf . In summary,
    Oracle 9i Database Release 2, Oracle 9i Database Release 1 and Oracle 8i
    Database (8.1.x) are all vulnerable and that "Risk to exposure is high, as a
    valid username and password is not needed in all cases to exploit this
    potential vulnerability."
    Cheers,
