A buffer overflow is a class of security vulnerability when the memory area allocated for a variable is exceeded by the data placed within it. Instead of being truncated to fit, the data is written as is, overwriting whatever was in memory directly after the affected variable. In many cases,...
Buffer overflow attacks have been there for a long time. It still exists today partly because of programmers carelessness while writing a code. The reason I said ‘partly’ because sometimes a well written code can be exploited with buffer overflow attacks, as it also depends upon the dedication...
A buffer overflow vulnerability occurs when you give a program too much data. The excess data corrupts nearby space in memory and may alter other data. As a result, the program might report an error or behave differently.
I am learning about Buffer Overflows (BOF) and came up with this piece of C code: #include <stdio.h> #include <stdlib.h> void win() { system("/bin/bash"); } int main() { char s[128]; scanf("%s",&s); printf("%s\n", s); return 0; } Using pwntools I...

Aptly named tonyhax, this exploit uses a classic buffer overflow found in the “Create Skater” mode inTony Hawk2, 3, and 4. When the game sees a custom character saved on the memory card it will automatically load the name field to show it on the screen, but it turns out the develo...

于是作者提出了一种针对Overflow的解决思路,引导符号化执行仅去探索我们关注的地方,并且最小化的符号化输入,以提高执行效率。 解决方法主要分为3步: 1. 静态分析 本文提出的一个观点是,Buffer Overflow更易容易发生在对数组的循环操作过程中,并且这些操作越复杂,程序员对与它的掌控能力越小,漏洞越可能发生。
