Cisco: Doh!

I'm not sure what to say about this story except... Doh!
You can check out the full story at The Register, or take a look at the original Cisco document, which surprisingly is dated April 20th, 2000. Here's a snippet:

"A defect in multiple Cisco IOS [Internet Operating System] software versions will cause a Cisco router to reload unexpectedly when the router is tested for security vulnerabilities by security scanning software programs. The defect can be exploited repeatedly to produce a consistent denial of service (DoS) attack,"

It's news items like this that really make a guy love his sysadmin job. With Cisco gear running a very large portion of the Internet, as well as corporate intranets, I imagine this isn't going to be an easy fix. Excuse me while I go check some of my Cisco gear...

Like what we're doing? Pay what you want to support TR and get nifty extra features.
