heap-buffer-overflow是一个由AddressSanitizer(ASan)检测到的运行时错误,表明程序试图访问堆内存中的一个已分配对象的超出其边界的内存区域。这通常发生在数组访问、字符串操作或指针运算等场景中,当索引或指针偏移量超出了合法范围时。 2. 导致heap-buffer-overflow错误的常见原因 数组越界:访问数组时,使用了超出其长度...

Sometimes due to code error, there is read or write from outside the buffer, such an error is usually hard to detect. Using this flag the compiler add some boundaries check, to ensure you won't use a buffer to reach outside of its allocation. what is heap-buffer-overflow? use an ...
While testing this program, I encountered a heap-buffer-overflow. I am aware that this error implies a segmentation fault. However, I am not sure where in the program this error arises. string gcdOfStrings(string str1, string str2) { const char *ptrI = str1.c_str(), *ptrJ =...

很容易想到利用堆溢出覆盖这个RTMPPacket的数组就可以了,但是这时候的堆布局数组是在可溢出的heap chunk的上方,怎么办?再发送一个CSID为20的 chunk 给客户端,ff_rtmp_check_alloc_array会调用realloc函数给数组重新分配更大的空间,然后数组就跑到下面去了。此时的堆布局如下 ...
