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 and 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 Flash Video module. It allows the RealPlayer to process files with Flash Video (FLV) type. Multiple remote code execution vulnerabilities have been reported in RealNetworks RealPlayer. The vulnerabilities are due to two integer overflow errors while parsing the ECMA Array and the Strict Array type data in FLV files. A remote attacker may leverage these vulnerabilities by enticing a target user to open a crafted FLV file. Successful exploitation would allow an attacker to execute arbitrary code in the security context of the logged in user and could cause an abnormal termination of the affected product.
