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. This includes MPEG-1 Audio Layer 3, commonly referred to as MP3 audio files. A remote buffer overflow vulnerability exists in RealNetworks RealPlayer application. The vulnerability is due to boundary errors when processing certain tags in MP3 files. A remote attacker can exploit this vulnerability by enticing the target user to open a crafted MP3 file. Successful exploitation would cause a heap-based buffer overflow that may lead to arbitrary code execution in the security context of the logged in user. In an attack case where code injection is successful, the behavior of the target is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the current logged in user. In an attack case where code injection is not successful, if the affected RealPlayer or RealOne Player process will terminate abnormally.
