|
|
|
|
|
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 <= Build 6667 are vulnerable.
