Maybe it’s just a bad dream, but it seems like 2008 has been a year of serious security issues, which have the potential to cause major problems on the Internet.
First, there was the OpenSSL vulnterability, which seems to greatly affect Ubuntu Linux (there is exploit code in the wild)
Then the DNS cache poisoning vulnerability was disclosed on 7/8/2008. Most systems had patches available within 3 or 4 days. Microsoft’s fix for that broke many installations of the ZoneAlarm firewall on Windows.
The combined effects of these two vulnerabities are significant, you may not be able to verify you are connected to the correct web site, even if the SSL connection appears to be good.
Keep up with those patches, and remember: Some user have even more basic problems
