Vulnerability Type: Exec Code 
CWE ID: CWE-254
Summary: Google Chrome before 44.0.2403.89 does not ensure that the auto-open list omits all dangerous file types, which makes it easier for remote attackers to execute arbitrary code by providing a crafted file and leveraging a user's previous *Always open files of this type* choice, related to download_commands.cc and download_prefs.cc.
