Descriptions

Relax-and-Recover (aka ReaR) through 2.7 creates a world-readable initrd when using GRUB_RESCUE=y. This allows local attackers to gain access to system secrets otherwise only readable by root.

Relax-and-Recover (a.k.a ReaR) hasta 2.7 crea un initrd world-readable cuando se usa GRUB_RESCUE=y. Esto permite a los atacantes locales obtener acceso a secretos del sistema que de otro modo sólo serían legibles por root.

A vulnerability has been identified in Relax-and-Recover (ReaR), where the use of GRUB_RESCUE=y results in the creation of an initrd that is readable by anyone. This flaw could potentially enable local attackers to obtain access to system secrets that are typically restricted to root privileges.

An update for rear is now available for Red Hat Enterprise Linux 8.
