CVE-2012-4453 dracut: Creates initramfs images with world-readable permissions (information disclosure)
Last modified: 2014-12-10 09:01:23 EST
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.
This issue was discovered by Peter Jones of the Red Hat Installer Team.
