UPDATE: The updated packages are now available in the official Fedora repositories. View this post for up-to-date details on how to install on your Fedora system.

Updated packages that resolve CVE-2014-6271 and CVE-2014-7169 (collectively known as “Shellshock”) have now been built for Fedora 19, 20 and 21 Alpha. These packages still need to make their way through the package release system and to the mirrors, but they should be available through the regular update channels shortly.

The new updated packages are named:

Fedora 21: bash-4.3.25-2.fc21
Fedora 20: bash-4.2.48-2.fc20
Fedora 19: bash-4.2.48-2.fc19
