Who is Vulnerable?
Vulnerability Description	RealPlayer is a media player developed by RealNetworks, Inc. The application is capable of playing back numerous formats of multimedia files. The WAV format is one of the supported audio formats. RealPlayer uses a plugin library audplin.dll to parse WAV files. A flaw exists in the way RealPlayer processes files encoded using the WAVE format. The vulnerability occurs when RealPlayer attempts to parse a crafted WAV file with an incorrect LIST chunk. An attacker can exploit this vulnerability to inject and execute arbitrary code with the privileges of the currently logged in user. In case of an attack where code injection and execution is successful, the behavior of the target is dependent on the intended purpose of the injected code. Any code injected into the vulnerable component would execute in the security context of the current user. In case of an attack where code injection is not successful, the RealPlayer application may terminate abnormally.
