RealNetworks RealArcade Installer 2.6.0.481

The RACInstaller.StateCtrl.1 ActiveX control in InstallerDlg.dll in RealNetworks GameHouse RealArcade Installer 2.6.0.481 performs unexpected type conversions for invalid parameter types, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via crafted arguments to the (1) AddTag, (2) Ping, (3) QueuePause, (4) QueueRemove, (5) QueueTop, (6) RemoveTag, (7) TagRemoved, or (8) message method.

RealNetworks GameHouse RealArcade Installer (aka ActiveMARK Game Installer) 2.6.0.481 and 3.0.7 uses weak permissions (Create Files/Write Data) for the GameHouse Games directory tree, which allows local users to gain privileges via a Trojan horse DLL in an individual game's directory, as demonstrated by DDRAW.DLL in the Zuma Deluxe directory.
