Root shell? Posted Jul 6, 2005 0:35 UTC (Wed) by Ross (subscriber, #4065) [Link] How can opening a file lead to opening a shell? They are fundamentallydifferent things. Does the program have buffer overflows or other unchecked input problems when reading the user log? Or does it actually execute the log file? If it's an input validation thing that should be fixed in addition to dropping priviledges.
