The RealNetworks RealArcade platform includes an ActiveX control (InstallerDlg.dll, version 2.6.0.445) that exposes a method named Exec via the StubbyUtil.ProcessMgr COM object. This method allows remote attackers to execute arbitrary commands on a victim's Windows machine without proper validation or restrictions. This platform was sometimes referred to or otherwise known as RealArcade or Arcade Games and has since consolidated with RealNetworks' platform, GameHouse.

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.

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.

Directory traversal vulnerability in RealArcade 1.2.0.994 allows remote attackers to delete arbitrary files via an RGP file with a .. (dot dot) in the FILENAME tag.

Integer overflow in RealArcade 1.2.0.994 and earlier allows remote attackers to execute arbitrary code via an RGS file with an invalid size string for the GUID and game name, which leads to a buffer overflow.
