heap-buffer-overflow是一个常见的内存错误,指的是在堆内存分配的空间中进行了越界访问。这种错误通常由程序尝试读取或写入超出其已分配内存范围的内存位置所引起。 分析可能导致heap-buffer-overflow错误的原因 数组或指针越界:在C/C++等语言中,如果访问数组或指针时索引超出了其有效范围,就会发生heap-buffer-overflow。
Dear libde265 developers, I used AFL++ to fuzz test dec265 and found some problems. To debug a program built with ASan, here is some output === ==2426872==ERROR: AddressSaniti...

这个ASan(AddressSanitizer)错误信息表示在你的程序中发生了“heap-buffer-overflow”(堆缓冲区溢出)错误。具体分析如下: 错误详情 错误类型: heap-buffer-overflow:表示对动态分配内存的写操作超出了该内存块的边界。 发生位置: 报错信息显示,程序在地址0xb3600ff8进行了写操作,但这个地址位于一个分配了40字节的内存区...

下面对比分析 ASAN 与 HWASAN 检测内存错误的技术原理: ASAN (AddressSanitizer): 使用shadow memory技术,每 8-bytes 的 application memory 对应 1-byte 的 shadow memory。 使用redzone来检测 buffer-overflow。不管是栈内存还是堆内存,在申请内存时都会在原本内存的两侧额外申请一定大小的内存作为 redzone,一旦访问到...

I'm running into an issue where when enabling ASAN I end up with a heap buffer overflow (at link time AFAICT), which does not occur when not enabling ASAN. I created issues with both the googletest and the nlohmann/json repos too, but I ...
This causedsnprintfto treat it as a null terminated string and access the null byte as part of its processing. And that caused ASAN to fail with theheap-buffer-overflowerror. Fix The fix is simple and is to not treat it as a null terminated string in thesnprintfcommand. And that is easi...
