DESCRIPTION:
Nicolas Robillard has reported a vulnerability in ZoneAlarm Pro and
ZoneAlarm Security Suite, which can be exploited by malicious people
to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the Ad-Blocking
feature (disabled by default) when processing JavaScript and can be
exploited by tricking a user into visiting a malicious web site
containing specially crafted JavaScript.
Successful exploitation causes the system to become unstable or stop
responding completely.
SOLUTION:
Update to version 5.5.062 or later via the "Check For Update"
feature.
