Kaminsky's DNS flaw affects such a wide variety of products that it's not surprising that there have been some glitches in the patch process. Earlier this week, DNS experts reported that the patch they'd created was slowing down performance on some high-traffic servers -- those that were being hit with more than 10,000 queries per second. On Friday, security vendor nCircle reported that Apple's fix for the DNS issue did not work properly.
Internet Systems Consortium President Paul Vixie calls the port translation problem a "big deal," but he said that despite some early skepticism, users are starting to understand the seriousness of the situation. When Kaminsky first discussed the problem, some security experts had said that the problem appeared to be simply a rehash of a known issue.
But after the bug was inadvertently disclosed last week, some skeptics changed their tune.
"This continues to be a mess," he said via e-mail. "But at least there are no more deniers out there muddying the waters with the 'overblown, not urgent' message."
