- * 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.
