Subsequent analysis found that Sock_put (SK) was called 2 times, resulting in a very common UAF (use-after-free) vulnerability. Now that you have a UAF vulnerability, the next step is to use UAF to control the kernel. Pingpong Root is ret2dir (ret2dir:rethinking

a verification method FIDO 2015 in 2.0. This system will become the framework of a new Internet authentication mechanism. In short, FIDO wants to use your mobile phone to verify your identity. The most understandable scenario is that when you log on to a website, the website will send a verification code to your mobile phone. You enter the verification code to log on without setting a password for the webs

multiple bus (such as USB. Most of the time, this type of driver controls the data sent from the user interaction interface, such as the keyboard, mouse, and game lever. Static Image architecture (STI) is not a driver at all, but a means of acquiring scanners and static cameras using micro drivers. STI currently supports SCSI devices, serial devices, parallel devices, and USB devices. STI is based on COM (Component Object Model ). 2.2 layered driver structure we already know that WDM uses a lay

It has been thought that C + + has a class reason is that the struct in C can not have constructors, destructors, inheritance and other functions, did not expect the struct can also implement these functions.Only the default keyword in class is private, and the default keyword in a struct is public.An example is given to illustrate some of the functions of implementing classes with structs.eg#include using namespace Std;Enum Breed {Golden,cairn,dandie,shetland,doberman,lab};//breed is a data typ

A large number of accounts and passwords that are easy to forget are a major by-products of the Internet. A few days ago, the payment vendor's PayPal Chief Information Security Officer, Barrett MichaelBarrett, said that the technology of using the account password to authenticate the user's identity "cannot survive for a few days. Barrett made the above statement at the recent InteropIT conference. Barrett said that the account and password technology will not be used for much time. In the futu

Note that Transfer objectIf an object is passed to the function, a reference is passed. If this reference is changed, the original object is changed.The following is an example of object assignment. var original = {name:'nicholas'}; var copy =original; copy.name;//'nicholas'; copy.name = 'Jason'; original.name;// 'Jason'; Modifying the copy attribute name is equiva

programming languages, it is called an associative array. The value can be either the original value or the object. Regardless of the type, they are property, and the property value can also be a function, when the property is called method.Custom objects in JavaScript (user-defined local objects) are mutable at any time. The properties of built-in local objects are also mutable. You can create an empty object first, and then add functionality to it when you need it. "Object literal notation (l
