Windows has added an extra set of data execution prevention security checks, also called software-enforced DEP, designed to mitigate exploits of exception handling mechanisms in Windows. Software-enforced DEP can run on any processor capable of running Windows XP SP2 and above. Should You Disable ...

使用VS Express 2012连接到质量中心的尝试会导致System.BadImageFormatException错误 、、、 我试图使用2012上的WPF应用程序连接到Quality。我的系统配置是Windows 7 64位。搜索类似的问题会给出一些解决方案,比如将项目目标平台设置为x86,但是这个解决方案对我来说并不管用。我收到错误了 使用CLSID检索组件的COM类工厂(...
Most likely, the process will crash within a microsecond with an exception like “Access Violation”, “Invalid Instruction”, “Divide by 0” or similar.Attackers look for this type of memory corruption to use as an entry point in their attacks; they may, for instance, “spray the heap”...

对于目前的大部分windows操作系统,其系统模块都受SafeSEH保护,可以选用未开启SafeSEH保护的模块来利用,比如漏洞软件本身自带的 dll文件, 这个可以借助OD插件SafeSEH来查看进程中各模块是否开启SafeSEH保护。除此之外,也可通过直接覆盖返回地址 (jmp/call esp)来利用。另一种方法,如果esp +8 指向EXCEPTION_REGISTRATION 结构...
简单的说,它的原理是检查异常处理是否安全(SEH-Safe Exception Handling)。它是完全通过软件支持的一种安全特性。在以后的安全编码实践中我们会专门讨论SEH。 硬件DEP,则是需要CPU提供支持的,同软件DEP相比,硬件DEP提供的保护更为全面。以后我们提到的DEP,都是指硬件DEP。 2.2 NX位 在80x86体系结构中,操作系统的内...
Opt your code into other available defenses like stack defense (/GS), safe exception handling (/SafeSEH), and ASLR (/DynamicBase)Thanks for your help in securing the web!Eric Lawrence Program ManagerUpdated 9/14/2009 to reflect that DEP/NX protection is enabled on Windows XP SP3. While Wind...
