-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of RealNetworks RealPlayer. User interaction is
required to exploit this vulnerability in that the target must visit a
malicious page.

module is responsible for handling the tfile, pnmm, cdda, protocol
handlers. While parsing a long argument ending with ".smil" an attacker
can overflow a buffer on the heap. This can be abused to execute
arbitrary code under the context of the user invoking the control.
