缓冲区溢出（Buffer Overflow）是一种常见的软件 安全漏洞 ，当程序向内存中的缓冲区写入超出预期长度的数据时，就会发生这种情况。正常情况下，程序会为数据分配特定大小的内存空间（即缓冲区）。

2016年3月13日 · On multiple occasions, I’ve called the help desk to report a buffer overflow popup dialog. This happens occasionally when I’m roaming (no dedicated computer; find and use any computer that works). The intent was to notify them of the affected system and of the environment and actions leading up to the buffer overflow dialog.

2024年12月16日 · A buffer overflow occurs when a program allocates too little memory for a given amount of data. The excess data then overwrites adjacent memory areas, which can contain sensitive information such as program flow data, process memory, or pointers.

An in-depth guide on a basic buffer overflow and the details behind developing an exploit for it.

2009年2月22日 · A buffer overflow is basically when a crafted section (or buffer) of memory is written outside of its intended bounds. If an attacker can manage to make this happen from outside of a program it can cause security problems as it could potentially allow them to manipulate arbitrary memory locations, although many modern operating systems protect ...

A buffer overflow can result in undesired behaviour, crashes, or even remote code executions. When a buffer overflow occurs, the extra data can overwrite adjacent memory locations, potentially altering the execution of the program.

Push the frame pointer (SFP) on the stack. local variables of the function (Locals). %ebp. %eip. Note that pop reads the top of the stack (what %esp is pointing to) and puts it into the specified register. *Note that ret is a bit more complex in practice, but we won’t worry about that for now.

Buffer overflow occurs when data exceeds the buffer's storage capacity, leading to data spilling over into adjacent memory spaces. This overflow can corrupt data, crash the program, or lead to the execution of malicious code if an attacker exploits the situation.

2013年3月5日 · We use ROP to turn off DEP (by adding the execute permission to the memory page that holds the stack) and then simply jump to our traditional shellcode payload. On Windows, this is usually a case of making a VirtualProtect() system call, loaded with the correct parameters to allow execution of the stack.
