Who is Vulnerable?
Vulnerability Description RealPlayer and RealOne Player are media player applications developed by RealNetworks, Inc. These applications are 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. One such module that is included with some players from RealNetworks is the SWF Flash module. It allows the RealPlayer to process certain types of Macromedia Flash (SWF) files. There exists a buffer overflow vulnerability in the RealNetworks RealPlayer product. The vulnerability is specific to parsing malformed Macromedia Flash (SWF) files. 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 process flow of the vulnerable application will be diverted to attacker supplied code. The result of such an attack is entirely dependent on the purpose of the injected code. In case of an attack where code injection is not successful, the affected application will terminate.
