Who is Vulnerable?
Vulnerability Description RealPlayer is a media player application developed by RealNetworks Inc. This application is capable of playing back numerous multimedia file formats. The application can open media files from local file system or network servers. RealPlayer has an extensible nature that allows it to handle different media file formats by way of external plugin modules. A remote code-execution vulnerability exists in RealNetwork's RealPlayer application. The vulnerability is due to an incorrect handling of the filename length in an IVR (Internet Video Recording) file. A remote attacker can exploit this vulnerability by enticing the target user to open a malicious IVR file, potentially causing arbitrary code to be injected and executed on the target. In case of an attack where code injection and execution is successful, the behavior of the target will depend on the intented purpose of the injected code. Any code injected will be executed within the security context of the currently logged in user. In case of an attack where code injection is not successful, RealyPlayer will terminate abnormally.
