Ignoring fields is useful if your input contains more fields than the model, and you do not want to have many special cases to work with these unused data fields.Automatically update objectsRealmobjects is real-time and automatically updates the view to the underlying data, which means that the object does not have to be refreshed.

JSON means JavaScript object Notation, which is a common format for data representation in JavaScript, and the JSON data format is much like the object in javascript:{"Name": "Value", "some": [1, 2, 3]}The difference is that, relative to the property name in the object, the key name in the JSON must be wrapped in quotation marks. This is only required in special attribute names when the object is famous:{"First name": "Dave"}.To parse a JSON data into a JavaScript object, it is best to use Json.

Firefox 31 ~ 34 Remote Command Execution Vulnerability Analysis 0x00 PrefaceSome time ago, the second brother promoted the scripting vulnerability to remote command execution in many browsers, almost all domestic browsers on the market, which has become a hot topic for many people. Indeed, in today's increasingly powerful underlying security protection environment, it is difficult to exploit vulnerabilities caused by stack overflow and UAF. However, i

strength rise and the current browser UAF vulnerability ZTE, there are a variety of vulnerability forms, but the basic idea of exploits has not changed much. There are only two forms: Download, execute, release, and execute, the ultimate goal of exploits is to execute a program. The purpose of anti-virus software detection and removal is to detect such behaviors and trigger alarms and prevent them from running. The final pseudocode for exploits is as

The vulnerability affects all versions of the Windows operating system, which is fixed by Microsoft on a 4 -month patch day, when an attacker gains access to a successful exploit . 0x01 Vulnerability Analysis Nils Sommer There is no description of the vulnerability in this case, and I think the crash scenario would be NULL Pointer

in heap overflow. The free function first determines whether the release tag is released based on the block tag, and then sets the release tag to 0, the length to 0, and the pointer to null, without UAF. The dump function prints the heap block content without exploiting the vulnerability. Leak libc_base The first idea is to leak the base address of libc. This vulnerability lies in the existence of a heap overflow vulnerability, which can be wri
