Descriptions

The SSH configuration in the Red Hat mkdumprd script for kexec-tools, as distributed in the kexec-tools 1.x before 1.102pre-154 and 2.x before 2.0.0-209 packages in Red Hat Enterprise Linux, disables the StrictHostKeyChecking option, which allows man-in-the-middle attackers to spoof kdump servers, and obtain sensitive core information, by using an arbitrary SSH key.

La configuración SSH en el script mkdumprd de Red Hat para kexec-tools, tal y como es distribuido en los paquetes kexec-tools 1.x anterior a 1.102pre-154 y 2.x anterior a 2.0.0-209 en Red Hat Enterprise Linux, desactiva la opción StrictHostKeyChecking, lo que permite a atacantes man-in-the-middle falsificar servidores kdump, y obtener información sensible del núcleo, mediante el uso de una clave SSH arbitraria.
