An information disclosure flaw was found in the way dracut, an initramfs root filesystem images generator, created initramfs images. When the root filesystem contained sensitive information (password based authentication for iSCSI systems or encrypted root filesystem crypttab password information), an attacker could use this flaw to obtain this information. Acknowledgements: This issue was discovered by Peter Jones of the Red Hat Installer Team.
This issue affects the version of the dracut package, as shipped with Red Hat Enterprise Linux 6. -- This issue affects the versions of the dracut package, as shipped with Fedora release of 16 and 17.
