`[Suggested description]  
Buffer overflow in ALZip 8.51 and earlier allows remote attackers to  
execute arbitrary code via a crafted DosDevice file.  
  
------------------------------------------  
  
[Additional Information]  
To reproduce this issue, create a file named "AUX.3.2.1.e.pwned" using  
normal user CMD via following syntax: type AUX >  
\\.\C:\ProgramData\AUX.3.2.1.e.PWNED  
  
later you will find that AUX.3.2.1.e.PWNED file has created in  
C:\ProgramData folder.  
  
If you just simply "right-click" that file, ALZip's file compression will  
cause Stack buffer overflow which allows remote attackers to execute  
arbitrary code.
