Systems Affecteds: All UniVerse versions with UV/ODBC
Explanation: Trying to make an invalid query the client crashes and make the server slow with 5sec to 2min lag what could crash the server. Expoit: Make a query accessing UV/ODBC (I've used CrystalReports all versions) and make a valid/invalid link between tables, it will make the server crash, the line will be locked and the file too. Resolution: Just boot the server, it will stop the lag and release the locked line and file
