"Multiple vulnerabilities have been reported in RealOne Player, RealPlayer, and Helix Player, which can be exploited by malicious people to compromise a user's system and delete files. A problem with malformed calls can be exploited to execute arbitrary code by embedding the player on a malicious website and making specially crafted calls."
