     Can we assume a patched version of Bash will be released
shortly?


It's in updates-testing now, and has enough karma that it should be
pushed stable the next time the packages are mashed.  See
https://admin.fedoraproject.org/updates/bash-4.3.22-3.fc21 for more

So, could someone explain the nature of the vulnerability?

https://securityblog.redhat.com/2014/09/24/bash-specially-crafted-environment-variables-code-injection-attack/

has a good writeup...

along with: http://lwn.net/Articles/613032/

So, is this one of the ways javascripts exec bash to install malware
or do other nasty stuff?
Google analytics web pages are full of info about javascripts that
install malware without user's knowledge or consent.
