Zone Labs Zone Alarm is prone to a weakness that permits the bypassing of the Advanced Program Control protection.
|
|
|
|
Reports indicate that applications can create a modal dialog box displaying HTML, which can then be redirected to a remote site.
|
|
|
|
This would allow a malicious program to bypass Advanced Program Control protection and send data to a remote attacker from a compromised computer.
|
|
|
|
It should be noted that this issue only presents itself if the Advanced Program Control setting has been enabled and the browser has been authorized to access the Internet.
