dracut: dracut: root code execution via unescaped error message written to sourced emergency hook script in die()

A flaw was found in dracut. The die error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOTPATH option, an attacker on the adjacent network who controls...
