The remote host is vulnerable to a buffer overflow.
The remote Windows host has RealPlayer software installed. There is a flaw in this version of the software that would allow an attacker to execute arbitrary code. An attacker exploiting this flaw would need to be able to convince a user to download and play a malicious media file. Upon execution, a local content-parsing bug would be triggered, enabling a local heap overflow and code execution.
Upgrade to version 220.127.116.112 or higher.
