NVD Description

Note: Versions mentioned in the description apply only to the upstream grub2 package and not the grub2 package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

A certain Debian patch for GNU GRUB uses world-readable permissions for grub.cfg, which allows local users to obtain password hashes, as demonstrated by reading the password_pbkdf2 directive in the file.
