Originalnachricht

Name        : livecd-tools
Product : Fedora 17
Version : 17.17
Release : 1.fc17
URL : http://git.fedorahosted.org/git/livecd
Summary : Tools for building live CDs
Description :
Tools for generating live CDs on Fedora based systems including
derived distributions such as RHEL, CentOS and others. See
http://fedoraproject.org/wiki/FedoraLiveCD for more details.

Update Information:

The livecd-tools package provides support for reading and executing
Kickstart files in order to create a system image. It was discovered
that livecd-tools gave the root user an empty password rather than
leaving the password locked in situations where no 'rootpw' directive
was used or when the 'rootpw --lock' directive was used within the
Kickstart file, which could allow local users to gain access to the
root account. (CVE-2013-2069)

Please note that livecd-tools is also used by appliance-tools to create
images used for virtual machines, USB based systems, and so on.
Additionally, the Python script components of livecd-tools have been
broken out into a separate package named python-imgcreate on some
distributions (such as Fedora).

Acknowledgements:

Red Hat would like to thank Amazon Web Services for reporting this issue.
Amazon Web Services acknowledges Sylvain Beucler as the original reporter.
