(If a user didn't know to enter a number on the first line, a second and third line will probably not help.) At least if you fgets(3) you know how many input lines your program will need, and you won't have any buffer overflows... Share Follow answered Oct 25, 2009 at 17:...
A buffer overflow can occur inadvertently or when a malicious actor causes it. A threat actor can send carefully crafted input -- referred to asarbitrary code-- to a program. The program attempts to store the input in a buffer that isn't large enough for the input. If the excess data i...
A buffer overflow attack exploits buffer overflow vulnerabilities. A buffer overflow occurs when the volume of data exceeds the storage capacity of the system buffer, thereby damaging the programstack, compromising the program, shutting down the system, or enabling the program to execute other instruct...
A buffer overflow or overrun is a memory safety issue where a program does not properly check the boundaries of an allocated fixed-length memory buffer and writes more data than it can hold. This causes data to overflow to adjacent memory space, overwrit
The theoretical shortest message that could // cause integer overflows is 512MB. The default limit is 64MB. Apps // should set shorter limits if possible. If warning_threshold is not -1, // a warning will be printed to stderr after warning_threshold bytes are // read. For backwards ...

I wanna to execute a large batch in order to improve throughput. But when I batch insert into a wide table which has lots of columns. So the batch sql will be very very long, and the client will check the param count, and then throw this error if param count overflow the range [Sho...
Upon first glance, the stack encountered in this scenario appears to indicate aVirtualQueryproblem. Further examination shows the MyVirusScanner functions on the stack. This virus vendor had an option supporting buffer overflow protection and had hooked a series of API calls. This stack shows the ...
