* - PRE AUTHENTICATION Eudora Qualcomm WorldMail 9.0.333.0 IMAPd Service            *
*   Preauthentication Buffer Overflow.                                              *
* - Tested on: Windows Server 2003 SP1.                                             *
* - SEH gets overwritten at 749 bytes when using UID command.                       *
* Only 79 bytes left after SEH, So the shellcode was placed before SEH              *
* and backward jump is used after SEH to execute the shellcode.                     *
* - Shellcode: shell_bind_tcp LPORT*4444 EXITFUNC*seh , Bad charcters are 0x00 0x7b *
