-- Vulnerability Details:
This vulnerability allows remote attackers to execute code on vulnerable
installations of RealNetworks RealPlayer. User interaction is required
in that a user must open a malicious file or visit a malicious web

allocation. This buffer can then subsequently be overflowed. This
vulnerability can result in arbitrary code execution under the context
of the currently logged in user.
