after setting is complete.5. Installing the ARM compilerAccess the shared folder through the PC and copy the compiler to the shared folder so that the virtual machine can also be accessed. Install the extracted files.6. Configure Environment variablesUse VI in the virtual machine to modify the PATH variable in the/root/.bash_profile file to path=path:home/bin:/opt/host/armv4l/bin/, after disk execution: Source/root/.bash_ Profile, the armv4l-unknown-linux-gcc will be automatically searched late

not, then change the machine to ...) ） Super Terminal information Experiment Box Results show The problems encountered during the experiment and the solutions. (1) Related software and driver installation problems We used a computer that already has ads and Jtag installed, which leads us to fail the first time we try to install ads, so ads need to be uninstalled and installed before they

2018-2019-1 20165228 "The foundation of Information security system Design" experimental report on Buffer Overflow Vulnerability Experiment Introduction:Buffer overflow attack: by writing to the program's buffer beyond its length content, causing buffer overflow, thereby destroying the program's stack, causing the program to crash or to make the program to execut

, addresses the value of the program counter PC② decoding: Read up to two operands from register, get Vala or Valb③ execution: The arithmetic/logic unit either executes the operation specified by the instruction, calculates the valid address of the memory reference, or increases or decreases the stack pointer. The resulting value is Vale④: Writes data to memory, or reads data from memory, and reads a value of Valm⑤ write back: Up to two results can be written to the register file⑥ Update PC: Set

in memory, because this location can overwrite the return address exactly after an overflow occurs. And strcpy(buffer+100,shellcode); This sentence tells us again, Shellcode is saved in buffer + 100 the position. Below we will detail how to get the address we need to add.Now we're going to get shellcode in memory addressEnter the command:$ gdb stack$ disass mainNext:7, according to the statement strcpy (buffer + 100,shellcode); We calculate Shellcode's address as 0xffffd2d0 (hex) + 0x64 (hex of

Refer to the GDB Reference Card GDB's most basic commands are: GdB Programm (Start gdb) B Set Breakpoints (4 breakpoints are set: Line breakpoint, function breakpoint, conditional breakpoint, temporary breakpoint) Run starts running the program BT Print function Call stack P View vari
