Check Point Software Technologies, maker of ZoneAlarm, on Wednesday said it is working with Microsoft to resolve an issue with one of the patches within the software maker's July 2008 Patch Tuesday release.
At issue is Microsoft Update KB951748 (MS08-037), which addresses a DNS flaw made public on Tuesday by security researcher Dan Kaminsky.
ZoneAlarm customers who have automatic update selected for Windows Update, and whose ZoneAlarm Internet-security level is set to 'high', will experience a loss of Internet connectivity upon reboot.
ZoneAlarm users without automatic update may wish to wait to install the update until the matter is resolved.
For those who have already installed the patch, Check Point recommended removing Microsoft Update KB951748 from their systems. Detailed instructions for doing this can be found on the ZoneAlarm Web site. Another option is to lower the ZoneAlarm Internet-security setting to 'medium', although Check Point said it does not recommend that measure.
