即汇总下来，代码可以分为6部分组成，包括：BSS区（未初始化的全局变量/静态变量区）、Data区（实始化的全局变量区）、Stack区（栈区）、heap区（堆区）、Code区（代码区）、const区（常量区）。一、BSS区和Data区 C语言编程中定义的全局变量、静态局部变量，就是分配在全局变量/静态变量区域，但是...

Code Area(代码区):程序代码指令、常量字符串、只可读。 Static Area(静态区):存放全局变量/常量、静态变量/常量。该区域的大小在程序一加载进内存的时候就已固定,但是静态变量的值是可以更改的。 Heap(堆):由程序员控制,使用malloc...
In aprevious article, I’ve discussed an old (but important) category of memory-corruption vulnerability called “stack buffer overflows”, and how we, as attackers, can exploit these vulnerabilities to take control of a remote program and make it run our shellcode. ...
Objects that survive the oldest generation, however, will still be considered in the oldest generation. In other words, survivors from generation 2 will be generation 2 objects; and survivors from LOH will be LOH objects (collected with generation 2). User code can only allocate in gene...
这也算是unlink的另一种用法,上一篇的总结中,unsafe_unlink通过unlink来直接控制地址,这里则是通过unlink来泄漏libc的信息,来进行进一步的攻击。流程也较为简单。 和house_of_lore操作有点像,也是通过修改victim的bk字段,不过我们做这个的主要目的不是返回一个可控的地址,而是将libc的信息写到了我们可控的区域。
The KERNEL_MODE_HEAP_CORRUPTION bug check has a value of 0x0000013A. This bug check indicates that the kernel mode heap manager has detected corruption in a heap. Důležité This article is for programmers. If you're a customer who has received a blue screen error code while...
If the function fails and you have specifiedHEAP_GENERATE_EXCEPTIONS, the function may generate either of the exceptions listed in the following table. The particular exception depends upon the nature of the heap corruption. For more information, seeGetExceptionCode. ...
如果函数失败,并且已指定 HEAP_GENERATE_EXCEPTIONS,该函数可能会生成下表中列出的任一异常。 有关详细信息,请参阅 GetExceptionCode。展开表 异常代码说明 STATUS_NO_MEMORY 由于缺少可用内存或堆损坏,分配尝试失败。 STATUS_ACCESS_VIOLATION 由于堆损坏或函数参数不正确,分配尝试失败。HeapReAlloc 返回的内存对齐方式...
