RealOne Player / RealPlayer Enterprise on the remote Windows host
suffers from several buffer overflows involving specially crafted
media files (eg, '.mp3', '.rm', '.SMIL', '.swf', '.ram', and '.pls'). 
If an attacker can trick a user on the affected system into opening
such a file or browsing to a specially crafted web page, he may be
able to exploit one of these issues to execute arbitrary code subject
to the user's privileges on the affected host." );
