Who is Vulnerable?
Vulnerability Description RealPlayer is a media player product by RealNetworks Inc. that supports a variety of open and proprietary multimedia stream and file formats. RealPlayer is available for many common hardware and software platforms such as Windows, Linux, Solaris, and so on. A vulnerability exists in the way that RealNetworks RealPlayer products handle specially crafted media files. A RM media file containing a very large data segment length, when opened by a vulnerable player, can cause a heap-based buffer to be overrun . An attacker exploiting this vulnerability can execute arbitrary code or cause a denial of service. In case of an attack where code injection is not successful, the vulnerable product crashes or does not respond to user interaction. Both of these conditions create a denial of service condition of the current RealPlayer process. In case of an attack where code injection and execution is successful, the behavior of the vulnerable product will depend on the intended purpose of the injected code. Any code injected will run with the privileges of the current user account. If the account being used to view the malicious RM file has administrator or elevated privileges, then code may execute in the context of the system.
