IdSan:一个基于身份的内存消毒器,用于模糊二进制文件

IdSan: An identity-based memory sanitizer for fuzzing binaries

Jos Craaijo

摘要:

大多数内存清理器通过在编译时检测程序来工作。只有少数的内存清理程序可以清理没有源代码的二进制程序。大多数是基于位置的,因此无法检测全局变量或堆栈上变量的溢出。在本文中,我们介绍了一个基于身份的内存消毒二进制AArch64程序,它不需要访问源代码。如果用户提供一些注释或DWARF调试信息以及动态分配的内存,它能够检测堆栈和全局变量的溢出。

英文摘要:

Most memory sanitizers work by instrumenting the program at compile time. There are only a handful of memory sanitizers that can sanitize a binary program without source code. Most are location-based, and are therefore unable to detect overflows of global variables or variables on the stack. In this paper we introduce an identity-based memory sanitizer for binary AArch64 programs which does not need access to the source code. It is able to detect overflows of stack- and global variables if the user provides some annotations or DWARF debugging information is available, as well as dynamically allocated memory.
