Subject: [PATCH] grub-install on EFI if forced
|
||||
|
||||
UEFI Secure Boot requires signed grub binaries to work, so grub-
|
||||
install should not be used. However, users who have Secure Boot
|
||||
disabled and wish to use the command should not be prevented from
|
||||
doing so if they invoke --force.

Subject: [PATCH] cmd/search: Rework of CVE-2023-4001 fix
|
||||
|
||||
The initial fix implemented a new flag that forces the grub cfg
|
||||
stub to be located on the same disk as grub. This created several
|
||||
issues such as RAID machines not being able to boot as their
|
||||
partition names under grub were different from the partition where
|
||||
grub is located. It also simply means that any machines with the
|
||||
/boot partition located on a disk other than the one containing grub
|
||||
won't boot.
|
||||
This commit denies booting if the grub cfg stub is located on a USB
|
||||
drive with a duplicated UUID (UUID being the same as the partition
|
||||
containing the actual grub cfg stub)
