The remote host has RealPlayer installed. There is a flaw in the remote version of this software which may allow an attacker to execute arbitrary code on the remote host, with the privileges of the user running RealPlayer.
To do so, an attacker would need to send a corrupted skin file to a remote user and have him open it using RealPlayer.
Solution : Upgrade to the newest version of this software
If you have uninstalled RealPlayer you may wish to delete the old registry key at SOFTWARE\RealNetworks\RealPlayer.
