Microsoft Security Update Leaves ZoneAlarm in a Mess
Check Point Software has issued a fix for its ZoneAlarm personal firewall products that revives Internet connections disabled by a
Microsoft security patch released a few days ago. The fix applies to the ZoneAlarm Internet Security Suite, Pro, Antivirus, Anti-Spyware and Basic Firewall editions of the product. It can be downloaded directly from Check Point's ZoneAlarm.com Web site.
Since last Tuesday, ZoneAlarm customers complained that access to the Internet was denied after installing MS08-037, a patch designed by Microsoft to correct a vulnerability in both the client and server Domain Name System packages within Windows. Earlier on Tuesday, a security researcher announced a massive, multi-vendor patch release to address a fundamental flaw in DNS that could allow attackers to spoof IP addresses.
Checkpoint instructed its users to uninstall the Microsoft security update or temporarily lower the firewall settings to "medium" while it prepared a way to fix the problem. CheckPoint released an update to ZoneAlarm, version 7.0.483, which solved the conflict late Wednesday evening.
