April 3, 2008 (Symantec Security Response Weblog) - "...Update: It appears that this vulnerability has been patched within RealPlayer version 11.0.2 (build 6.0.14.802), which is now available for download. It contains version 6.0.10.50 of the rmoc3260.dll file, which we have determined no longer contains the vulnerability. Current RealPlayer users can use the Check for Update utility, which will also install a version of the .dll file that is no longer vulnerable to this exploit."
