From the boffins at The Register, "A bug discovered in the widely used Bash command interpreter poses a critical security risk to Unix and Linux systems – and, thanks to their ubiquity, the wider internet.It lands countless websites, servers, PCs, OS X Macs, various home routers, and more, in danger of hijacking by hackers".
 
Updated binaries are already coming online.
As I understand it, the issue is that the OSes in question are set up with environment variables that invoke /bin/bash. It's not simply a problem of someone somehow remotely invoking a shell script; the systems will probably do it on their own as normal operation. Even the most attentive admin in the world probably never went back and re-wrote those scripts for ksh or zsh.

I suspect this is going to be a problem for networked appliances and embedded systems for years to come.
 
Hmmm...so ESXi must be affected to. We have several setups running on this at many customers' locations.

All the servers I maintain at the office run on Server 2012 R2, so I'm clear on this one. Except my two VM that only crunch FAH units. I'll update them during the week-end if a fix becomes available.
 
This one actually made the morning news show here in Oz... Except it was completely incorrect (noting all systems including windows were affected), that AV will pick up malicious actions, etc...

But it was nice to see most Linux distro's packaging the fix very rapidly... (All our systems at work were patched yesterday, not that any affected systems were internet facing).

Like Merc mentions, this will be a problem with lots of embedded devices, and I wonder how many el-cheapo (and not so cheap) web hosting services are going to be hit as well, since you're relying on their admins to patch the system?
