Our investigation so far has shown that no other customers are affected by this issue.
"We’re still investigating this issue but we encourage customers who are using ZoneAlarm to review the appropriate ZoneAlarm Web site and Check Point Endpoint customers to review the appropriate Check Point Web site for the latest guidance or software updates and factor this information into your risk assessment, testing, and deployment planning."
