Hi. I know a lot of people are surprised by this little exploit but this is a well documented case in ldd. I remember this coming up as a bullet point at a local LUG meeting back in 1997 when we were installing Slackware on a box.
Needless to say, this really is an educate yourself deal as opposed to a "fix this, fix this!" exploit. You can head over to TLDP and see a clear warning about this.
I applaud the author for reminding everyone about this important issue, but (in my opinion) it really isn't a problem with ld-linux.so per se. When an executable says they are needing a different loader, the natural behavior should be to load the external loader. That alone should ring sysadmin bells, an external loader is being used...Do I trust it? All in all it comes down to a sysadmin watching their back and understanding how things work.
"All in all it comes down to a sysadmin ... understanding how things work."
Never forget the vast number of clueless people employed as system administrators.

I am being sponsored by Syntress since 2007! They bought me an amazing dedicated server to run catonmat on. If you're looking web services in Chicago area, I highly recommend the Syntress guys!
I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my Amazon wish list, if you're curious about what I have planned reading next, and want to surprise me. :)
