The problem can be exploited for example through a malformed ZPL file containing a http link to a file with PLS extension which will force the program to use wsprintf for building the "Unable to play [%s]" error message. ####################################################################### =========== 3) The Code =========== http://aluigi.org/poc/zoomprayer.zpl ####################################################################### ====== 4) Fix ====== The next beta will contain the fix. ####################################################################### --- Luigi Auriemma http://aluigi.org
