Who is Vulnerable?
Vulnerability Description	RealPlayer and Helix Player are media players developed by RealNetworks, Inc. These applications are capable of playing back numerous multimedia file formats. They support a streaming slide show technology called RealPix that allows for the creation of presentations that include image content. The RealPix format is a proprietary RealNetworks multimedia format. A format string vulnerability exists in the RealNetworks RealPlayer and Helix Player products. A remote user may exploit this flaw by supplying a crafted RealPix multimedia file to a vulnerable target. The vulnerability may be exploited to divert process flow of the vulnerable application and execute arbitrary code in the security context of the current user running the vulnerable product. In an unsuccessful code injection attack case, the vulnerable application may unexpectedly terminate as a result. In a successful attack scenario, arbitrary code may be injected and executed on the target system. In such a case, the behaviour of the target system is dependent on the intent of the malicious code.
