The remote host runs the Pinnacle ShowCenter web based interface.

The remote version of this software is vulnerable to a remote denial of 
service due to a lack of sanity checks on skin parameter.

With a specially crafted URL, an attacker can deny service of the ShowCenter 
web based interface.

Solution: Upgrade to the newest version of this software.
