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 ...
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...
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...

看过asan的源码,他采取的是替换free和malloc函数,所以我这里也替换free和malloc,在malloc的时候多分配一个size_t大小用于存储malloc的buffer大小,并放置在buffer前。 在free的时候获取存储的buffer大小进行memset,后在释放。 为测试代码添加了signal处理函数(如果不添加处理函数会显示Segmentation fault: 11),当程序崩溃的...
