Every once in a while (when I think out loud and people overhear me) I am forced to explain what a buffer overflow is. Because I can't really think of a good metaphor, I end up spending about 10 minutes explaining how (vulnerable) programs work and memory allocation, and then have ab...
Are there any moral theories, according to which we should give greater moral consideration to non-human animals than to human beings? Number of complete binary unordered tree-factorizations of n Prepare Bitlocker protected PC for disposal Is there a sizeable difference in the number of polling...
the program stops execution immediately and displays a corresponding error message. Stack overflow attacks are the most common type of buffer overflow attacks. For a stack overflow attack to be carried out, programs must write data to the stack and the size of the written data must not be cont...
Start by examining the code you use during development. Programming languages vulnerable to buffer overflow attacks include: Assembly C/C++ Fortran These languages come with no built-in protection, and they don't allow for routine checks for overflows. Next, examine your code. It'seasier for a...

The unit of work for a worker is a request (SQL Server 2000: UmsWorkRequest, SQL Server 2005: SOS_Task). A request can be loosely equated to a batch (IE. SQLBatch:Started trace event). Take the following as an example. SELECT @@VERSION GO SELECT ‘This is a test’ GO ...
I searched many areas (from google to msdn forum) for the last 1.5 months on application crash with ExceptionCode: c0000409 (Stack buffer overflow) but nothing seems similar to what I have. Most of the queries manged to find something wrong with unmanged string management or wrong parameters...

If I add an extra 30 bytes to my "jsonMessage" everything works. Where I'm wrong? Which is the best way to compute the buffer length required by cJson? Thanks! This will probably change in a future version of cJSON, but for now there is now way around that. ...
